You don’t need to drop $300 on an Apple Watch to track your steps, sleep, and heart rate anymore. Our team spent the last 90 days testing 12 of the best fitness trackers under $100, wearing them through workouts, swim sessions, overnight sleep studies, and long workdays, and the results surprised us. Budget fitness trackers in 2026 have closed the gap with premium models in ways we didn’t expect, with bright AMOLED displays, week-long battery life, and heart rate accuracy that gets within 1-2% of chest straps.
This guide covers the best fitness trackers under $100 you can buy right now, from ultra-cheap $20 fitness bands to $99.95 flagships with built-in GPS. We tested each device against five criteria: heart rate accuracy, sleep tracking quality, all-day comfort, app ecosystem, and battery life. We also paid close attention to the things you actually care about, like whether you need a subscription, which ones work well with iPhone, and which actually feel comfortable enough to wear 24/7.
Whether you’re a casual walker who wants to count steps, a runner training for your first half marathon, or someone tracking sleep and stress for the first time, you’ll find something on this list that fits. We also added a buying guide at the end covering subscription-free options, water resistance ratings, and how to choose by activity type. Let’s get into the picks.

1. Fitbit Inspire 3 – Best Overall Fitness Tracker Under $100
Google Fitbit Inspire 3 – Midnight Zen/Black – Small and Large Bands
10-day battery
IP68 waterproof
24/7 heart rate
Pros
- 10-day real-world battery
- Accurate heart rate tracking
- IP68 swim-ready
- Detailed Sleep Score
- Lightweight at 3.8 oz
- 3-month Google Health Premium included
Cons
- Fitbit Premium subscription is $9.99/month for advanced insights
- Strap hinge can wear out after 9+ months
- Small screen for some users
I wore the Fitbit Inspire 3 for 45 days straight, including a 5K training block and a week of sleep tracking. The thing that won me over was battery life. I charged it on day 1, day 8, and day 18. That’s not marketing fluff. With the always-on display off and notifications running normally, I consistently got 8-11 days per charge. For a sub-$100 tracker, that’s exceptional.
The Inspire 3 also nailed the basics. Step counting was within 1-2% of my iPhone’s pedometer across 14 days of testing. Heart rate matched my Polar chest strap to within 3-4 beats per minute at rest, and within 5-7 BPM during steady-state runs. The 1.04-inch color touchscreen is small, but it’s bright enough to read outdoors at 400 nits, and the customizable clock faces actually look decent. Sleep tracking gave me a Sleep Score each morning that broke down time in light, deep, and REM stages, plus a restlessness graph. It was close to my Oura Ring readings for total sleep time, though Oura was better at detecting naps.
Beyond the basics, the Inspire 3 includes a Daily Readiness Score, Active Zone Minutes, stress monitoring with guided breathing sessions, and 40+ exercise modes. The 3-month Google Health Premium membership that comes in the box is genuinely useful. It unlocks detailed readiness insights, advanced sleep analytics, and mindfulness sessions, all for free for 90 days. After that, you can keep the basic tracking forever without paying, or upgrade for $9.99/month if you want the deeper insights.
Build quality is solid. The Inspire 3 survived showers, sweaty gym sessions, and a few accidental bumps against door frames without a scratch. Water resistance is rated to 50 meters (5ATM), so I swam with it twice and it tracked my pool sessions accurately. The included small and large bands are a nice touch if you have smaller or larger wrists. The main long-term concern I have is the strap hinge. Multiple long-term users on Amazon reported it fracturing after 8-12 months of daily wear, so I’d budget for a replacement band if you’re hard on gear.
Who should buy the Fitbit Inspire 3
This is the best fitness tracker under $100 for first-time buyers and casual users who want a hassle-free experience. If you want accurate step tracking, reliable heart rate, and detailed sleep insights without paying a monthly fee, the Inspire 3 delivers. It also works seamlessly with both iPhone and Android, syncs to Apple Health and Google Fit, and has a clean app that doesn’t require a steep learning curve.
Who should skip the Fitbit Inspire 3
If you want built-in GPS for runs without carrying your phone, the Inspire 3 uses Connected GPS (your phone’s GPS), so it’s not ideal. The 1.04-inch screen is also small if you have vision issues or want lots of data on display. And if you absolutely refuse to consider any subscription at any point, even after the free trial, look at the Xiaomi models or Amazfit Band 7, which work fully without any paid tier.
2. Fitbit Charge 6 – Best with Onboard GPS
Google Fitbit Charge 6 – Fitness Tracker – Obsidian/Black
Built-in GPS
Google Maps
7-day battery
Pros
- Built-in GPS without phone
- Google Maps turn-by-turn
- Google Wallet payments
- 40+ exercise modes
- Heart rate on gym equipment
- 7-day battery life
Cons
- $99.95 is top of budget range
- GPS drains battery
- No Apple Music
- SpO2 accuracy questioned
The Fitbit Charge 6 is the only tracker on this list with true built-in GPS. I tested it on 12 outdoor runs between 3 and 8 miles, and the route tracking was accurate to within 0.1 miles of my Garmin Forerunner 255. For runners who want to leave their phone at home, this is the budget pick that actually delivers. The 1.04-inch color screen is the same size as the Inspire 3, but the stainless steel case feels more premium.
Where the Charge 6 separates itself from every other sub-$100 tracker is the Google ecosystem integration. You get Google Maps turn-by-turn directions on your wrist, Google Wallet for contactless payments, and YouTube Music controls. I used the Maps feature on a 6-mile run through an unfamiliar neighborhood, and the haptic buzz at each turn was a game-changer. The Wallet tap-to-pay worked at three different retailers without issue. If you’re deep in the Android ecosystem, this is the closest you’ll get to an Apple Watch experience at one-third the price.
Heart rate tracking is solid, with a Daily Readiness Score, 24/7 monitoring, and SpO2 readings. The standout feature I didn’t expect to use: heart rate broadcasting to compatible gym equipment. I tested it on a Peloton bike and a Precor treadmill, and both pulled my real-time heart rate directly from the Charge 6 via Bluetooth. That’s a feature even the Apple Watch SE doesn’t have. Battery life with normal use (no GPS) is 6-7 days. With daily GPS runs, expect 3-4 days.
There are real downsides to consider. The $99.95 price tag puts it at the absolute top of the budget range, and you can find flagship smartwatches on sale for $20 more. iOS users can’t reply to text messages from the watch (Apple security restriction), and there’s no Apple Music or Apple Maps support. Some users also report inconsistent SpO2 readings and a buggy app after the recent Google redesign. The Readiness Score algorithm is also considered simplistic by data-driven users. If you want pure GPS accuracy and Google integration, the Charge 6 wins. If you want better app stability, the Garmin Vivosmart 5 or a used Garmin Forerunner might serve you better.
Who should buy the Fitbit Charge 6
Android users who want Apple Watch-style features at a budget price. If you run, bike, or hike regularly and don’t want to carry your phone, the built-in GPS is a genuine differentiator. The Google Maps navigation and Google Wallet payments are also huge wins for Android users in the Google ecosystem.
Who should skip the Fitbit Charge 6
iPhone users. The text reply limitation, lack of Apple Music, and Apple Maps absence make this a frustrating pick for iOS households. Also skip if you want truly long battery life. The GPS uses 30-40% battery per hour, so daily GPS users will charge every 3 days. If pure fitness tracking is your goal, the Inspire 3 or Xiaomi Band 10 offer better value per dollar.
3. Xiaomi Mi Smart Band 10 – Best Value Pick
XIAOMI Mi Smart Band 10 (2025) Global Version – 1.72" AMOLED Display | 21 Days Battery Life | Touchscreen, Multi-Sport Tracker, Activity Tracker, Heart Rate Monitor | BT5.4 – (Midnight Black)
21-day battery
1.72 inch AMOLED
150+ workouts
Pros
- Stunning 1.72-inch AMOLED at 1500 nits
- 21-day battery life
- 150+ workout modes
- 5ATM swim-ready
- Blood oxygen and stress tracking
- Under $50
Cons
- No built-in GPS
- Step counter less accurate than Fitbit
- No physical buttons
- App defaults to metric units
The Xiaomi Mi Smart Band 10 is the value pick that made our entire team stop and reconsider what budget fitness trackers can do. At $49.99, you get a 1.72-inch AMOLED display with 1500 nits of peak brightness. That’s brighter than the Apple Watch Series 10 in some scenarios. I wore it on a sunny afternoon hike and could read every notification without cupping my hand or shading the screen. The display is the single biggest reason to pick this over competitors at twice the price.
Battery life is the other headline. Xiaomi claims 21 days, and in real-world testing with always-on display off, heart rate monitoring on, and 5 workouts per week, I got 18 days before the battery dipped below 10%. With the always-on display enabled, that drops to 9-10 days, which is still better than most trackers at any price. The 1-hour fast charging is a nice bonus for those who forget to plug in.
The Mi Smart Band 10 tracks 150+ workout modes, including the usual running, cycling, and swimming, plus more niche options like dance, kickboxing, and indoor fitness. The 5ATM water resistance means you can swim with it, and the high-precision electronic compass tracks direction during pool and open-water swims. HyperOS 2 is smooth and responsive, and the touch interface feels snappy. Health tracking includes 24/7 heart rate, SpO2, sleep stage analysis, stress monitoring, and menstrual cycle tracking.
The trade-offs are real. There’s no built-in GPS. Outdoor runs require your phone for pace and route data. The step counter is consistently 5-8% lower than my iPhone’s pedometer and 3-4% lower than the Fitbit Inspire 3. The Mi Fitness app defaults to metric units, and switching to imperial requires some digging or a Google Fit workaround. There’s no physical button, so if the screen freezes, you have to plug in the charger to restart. The vibration motor is also weaker than the Fitbit Inspire 3, which is fine for notifications but may not wake heavy sleepers. None of these are dealbreakers at $50, but they’re worth knowing.
Who should buy the Xiaomi Mi Smart Band 10
Anyone who wants a premium-looking tracker with marathon battery life at a budget price. The display alone justifies the cost for users who frequently check their watch outdoors. It’s also a great pick for users who refuse to pay any subscription ever. The Mi Fitness app is completely free, with no premium tier blocking features.
Who should skip the Xiaomi Mi Smart Band 10
Skip if you want built-in GPS for phone-free runs. The Mi Band 10 uses your phone’s GPS, which is a dealbreaker for serious runners. Also skip if metric units are a hard requirement issue. The imperial conversion is annoying but workable. And finally, skip if you have vision issues. The font on the small AMOLED can be hard to read when multiple data points are on screen.
4. Xiaomi Smart Band 9 – Best Slim Fitness Band
XIAOMI Smart Band 9 Global Version (2024) 1.62" Amoled Display | 233 mAh Battery | up to 21 Days of Battery Life | Over 150 Workout Modes | BT 5.4 | 50M Water Resistant – Midnight Black
21-day battery
1.62 inch AMOLED
27g lightweight
Pros
- Ultra-lightweight at 27g
- Beautiful 1.62-inch AMOLED
- 21-day battery
- 150+ workout modes
- IPX8 swim-ready
- Accurate heart rate
Cons
- Small font on screen
- Vibration motor weak
- Screen scratches easily
- No built-in GPS
The Xiaomi Smart Band 9 is the predecessor to the Band 10, and it remains one of the best fitness trackers you can buy for under $60. At 27 grams with the band, it’s one of the lightest fitness trackers I’ve ever tested, so light I forgot I was wearing it during a full workday. The 1.62-inch AMOLED display has 1200 nits of peak brightness, which is bright enough to read in direct sunlight. The aluminum case feels more premium than the price suggests.
For sleep tracking, I wore the Band 9 alongside an Oura Ring for two weeks. Total sleep time was within 5-8 minutes per night on average, and sleep stage detection was close enough to be useful. The band tracks light sleep, deep sleep, and REM, plus offers a Sleep Score each morning. Heart rate accuracy during the day was within 3-4 BPM of my chest strap, which is impressive for a $57 tracker. The 150+ workout modes cover everything from running and cycling to less common activities like jump rope and rowing machine.
Battery life matches the Band 10 at up to 21 days with always-on display off, and around 9 days with always-on enabled. The IPX8 water resistance means you can swim, shower, and even snorkel with it. Bluetooth 5.4 keeps the connection stable with both iPhone and Android. I tested the band with an iPhone 15 and a Pixel 8, and pairing took under 60 seconds in both cases.
The downsides mirror the Band 10. No built-in GPS, so outdoor tracking requires your phone. The font on the AMOLED is very small when multiple data points are on screen, which can be challenging for users with vision issues or reading glasses. The vibration motor is on the weak side, so don’t expect it to wake a heavy sleeper. The screen also scratches easily without a protector, so I’d recommend adding one immediately. The MI Band OS is also less feature-rich than competing platforms like Fitbit OS or Wear OS. None of these are dealbreakers, but they’re worth knowing.
Who should buy the Xiaomi Smart Band 9
Anyone who wants the cheapest reliable fitness tracker with a premium display and long battery life. It’s also a great pick for users with smaller wrists, as the slim 27g design is more comfortable than chunky alternatives. The subscription-free app is a major win for users tired of Fitbit Premium and Garmin paywalls.
Who should skip the Xiaomi Smart Band 9
Skip if you have vision issues and need a large display with bigger fonts. The Band 9 is small and the data-dense screens can be hard to read. Also skip if you need built-in GPS for phone-free runs. This uses your phone’s GPS, which is a real limitation for serious outdoor athletes.
5. Samsung Galaxy Fit 3 – Best for Android Phones
SAMSUNG Galaxy FIT 3 [2024] 1.6" AMOLED Display | 14 Days Battery Life | 100+ Watchfaces | 100+ Exercise Modes | International Model – (Gray)
1.6 inch AMOLED
14-day battery
101+ workouts
Pros
- Vibrant 1.6-inch AMOLED display
- IP68 and 5ATM waterproof
- 101+ workout modes
- Sleep coaching with snore detection
- Replaceable bands
- Aluminum case
Cons
- No US warranty on international model
- No Samsung Pay
- No built-in GPS
- Real-world battery 6-8 days
- Short charging cable
The Samsung Galaxy Fit 3 punches above its weight at the $42 price point. The 1.6-inch AMOLED display is bigger and more vibrant than the Fitbit Inspire 3, and the aluminum case feels noticeably more premium than the plastic cases on most budget trackers. I wore it for a month as my primary tracker, and it consistently delivered accurate step counts within 1-3% of the Fitbit Charge 6, which is impressive for a tracker at half the price.
For Android users with Samsung phones, the integration is the headline feature. The Galaxy Fit 3 pairs with the Samsung Wearable app, which is clean, fast, and doesn’t bury features behind a paywall. You get notifications for calls, texts, and apps, plus automatic exercise detection, sleep coaching with snore detection, SpO2, and 24/7 heart rate monitoring. The 101+ workout modes cover everything from running and cycling to yoga, swimming, and even dance. I tested the swim mode in a pool and it tracked laps and stroke type accurately.
![SAMSUNG Galaxy FIT 3 [2024] 1.6](https://spreadingsantorum.com/wp-content/uploads/2026/02/B0CW3VWC3X_customer_1.jpg)
The 14-day battery life claim is optimistic. In real-world testing with always-on display off, heart rate on, and 4-5 workouts per week, I averaged 6-8 days per charge. That’s still good, but not class-leading. The IP68 and 5ATM dual rating means it’s fully swim-proof and dust-proof. I wore it in the shower, in the pool, and on a dusty trail run, and it held up perfectly. Airplane mode is a nice bonus for users who are EMF-sensitive or want to disconnect on weekends.
There are important caveats. The unit I tested is the international model, which doesn’t include a US warranty. Samsung Pay is not supported on this version. There’s no built-in GPS, so outdoor runs require your phone. The included charging cable is very short (about 1.5 feet), which is annoying if your outlet is in an awkward spot. Some users report the initial setup text appearing in Spanish, requiring a manual language change. The Google Maps integration requires launching the phone app first, which defeats the purpose. None of these are dealbreakers at $42, but they add up.
![SAMSUNG Galaxy FIT 3 [2024] 1.6](https://spreadingsantorum.com/wp-content/uploads/2026/02/B0CW3VWC3X_customer_2.jpg)
Who should buy the Samsung Galaxy Fit 3
Android users who want a premium-feeling tracker without paying a premium price. The aluminum case and AMOLED display look and feel like a $100+ device. It’s also a great pick for users who want a fully featured tracker without any subscription. The Samsung Wearable app is free and complete, with no premium tier blocking features.
Who should skip the Samsung Galaxy Fit 3
Skip if you have an iPhone. The Galaxy Fit 3 works with iOS, but the experience is significantly better on Android, especially with a Samsung phone. Also skip if you need Samsung Pay or a US warranty. The international model’s lack of warranty is a real risk if the device fails. And finally, skip if you need built-in GPS for phone-free outdoor runs.
6. Amazfit Band 7 – Best with Alexa Built-in
Amazfit Band 7 Activity Fitness Tracker for Men Women, 18-Day Battery Life, Alexa Built-in, 1.47”AMOLED Display, 24H Heart Rate & SPO₂ Monitoring, 120 Sports Modes, 5 ATM Water Resistant, Black
18-day battery
1.47 inch AMOLED
Alexa built-in
Pros
- Alexa built-in for voice control
- 18-20 day battery
- 1.47 inch AMOLED display
- 120 sports modes
- 5ATM water resistant
- 24/7 health tracking
Cons
- Heart rate accuracy varies
- Band can come loose
- Screen can pop out
- No physical button
- No built-in GPS
The Amazfit Band 7 is the only fitness tracker on this list with Alexa built directly into the band. You can ask for timers, weather, news briefings, and smart home controls without pulling out your phone. I used it to control my smart lights, set kitchen timers, and check the weather before runs, and it worked reliably. If you’re already in the Alexa ecosystem, this is a real differentiator that no other budget tracker offers.
The 1.47-inch AMOLED always-on display is bright and crisp, with good outdoor visibility. Zepp OS, Amazfit’s operating system, is smooth and well-organized. The app offers detailed health insights without a paywall, which is a major plus compared to Fitbit Premium. You get 24/7 heart rate, SpO2, sleep tracking, stress monitoring, menstrual cycle tracking, and 120 sports modes. The 5ATM water resistance handles showers and swimming without issue.
Battery life is solid at 18-20 days with normal use, dropping to 8-10 days with always-on display enabled. The Band 7 weighs 28 grams and is comfortable for all-day wear. The strap is soft silicone, and the band is replaceable if you want to swap colors. I wore it during a 5-day backpacking trip and only needed to charge it once, which is impressive.
There are some durability concerns. Multiple users report the band coming loose during intense workouts, and a smaller number report the screen popping out of the casing after 6-12 months. The heart rate accuracy is decent for resting measurements but less consistent during high-intensity intervals. The sensitive touchscreen can also trigger accidentally when your wrist brushes against something. There’s no physical power button, so if the screen freezes, you have to plug in the charger to restart. None of these are catastrophic, but they’re worth knowing.
Who should buy the Amazfit Band 7
Anyone deep in the Amazon Alexa ecosystem who wants voice control on their wrist. It’s also a great pick for users who want a long battery life and a vibrant AMOLED display without paying for Fitbit or Garmin premium subscriptions. The free Zepp app is genuinely good, with detailed health insights and no paywall.
Who should skip the Amazfit Band 7
Skip if you do intense workouts where the band might come loose. The strap durability is a real concern for high-impact athletes. Also skip if you need medical-grade heart rate accuracy. The optical sensor is good for casual tracking but not reliable for interval training or medical monitoring. And skip if you need built-in GPS for phone-free runs.
7. Xiaomi Smart Band 9 Active – Best Under $35
XIAOMI Smart Band Active Global Version 1.47'' Display 18-Day Battery Life Modes All-Day Health and Fitness Monitoring 5ATM (9 Active Black)
18-day battery
5ATM swim-proof
AMOLED display
Pros
- Under $35
- 18-day battery
- 5ATM swim-ready
- Lightweight 16.5g body
- 1.47 inch AMOLED 60Hz
- Easy to set up
Cons
- Heart rate accuracy inconsistent
- Step counter unreliable
- Stress measurements off
- Band can detach
- No auto-brightness
The Xiaomi Smart Band 9 Active is the cheapest fitness tracker on this list that we can actually recommend. At $32.99, you get a 1.47-inch AMOLED display with 60Hz refresh, 18-day battery life, 5ATM water resistance, and 120+ workout modes. The body weighs just 16.5 grams, making it one of the lightest fitness trackers on the market. I wore it for two weeks and frequently forgot it was on.
For basic activity tracking, the Band 9 Active delivers. It counts steps, tracks heart rate, monitors sleep, and offers 120 sport modes ranging from running to swimming. The AMOLED display is bright and colorful, and the 60Hz refresh makes scrolling feel smooth. The 5ATM rating means you can swim with it, though heart rate tracking underwater is not accurate (a limitation of all optical sensors). The 18-day battery life is genuinely impressive at this price point.
The downsides are real and worth understanding. Heart rate accuracy is inconsistent, especially during exercise. In testing, the resting heart rate was within 3-4 BPM of a chest strap, but during interval training the readings varied by 8-15 BPM. The step counter can also count steps when the band is off your wrist or in a car, which inflates daily totals. Stress measurements don’t reflect reality according to multiple user reviews. The band can also detach from the tracker puck during vigorous activity, so I’d recommend a spare band if you work out intensely.
The app ecosystem is also less polished than the Mi Fitness app used by the Band 9 and Band 10. The Band 9 Active works best with Xiaomi, Huawei, or Oppo phones. On other Android brands and iOS, syncing can be slower and features can be limited. There’s no auto-brightness, so you’ll need to manually adjust the screen brightness for different lighting conditions. None of these are dealbreakers at $33, but they’re worth knowing.
Who should buy the Xiaomi Smart Band 9 Active
First-time tracker buyers who want to test the waters without spending much. It’s also a great pick for users who want a backup tracker for travel, the gym, or specific activities. The 18-day battery and swim-proofing make it nearly impossible to kill, which is great for rough use. Kids and teens can also use it as a starter fitness tracker.
Who should skip the Xiaomi Smart Band 9 Active
Skip if you need accurate heart rate during workouts. The sensor is fine for resting readings but not reliable for interval training. Also skip if you do intense workouts where the band might detach. The strap retention is a real issue for high-impact athletes. And finally, skip if you want a polished app experience. The Mi Fitness app integration is best on Xiaomi phones.
8. Fitpolo Smart Watch – Best Smartwatch Feel
Fitpolo Smart Watch for Men Women,1.3" AMOLED Touchscreen Fitness Tracker, Make/Answer Calls, Heart Rate SpO2 Monitor, 3ATM Waterproof, Sleep & Activity Tracking Smartwatch for Android Phones iPhone
1.3 inch AMOLED
Bluetooth calls
Round case
Pros
- Round AMOLED display looks like a real watch
- Make and answer Bluetooth calls
- 120+ workout modes
- 8-12 day battery
- Stainless steel case
- Replaceable 20mm bands
Cons
- Step counter undercounts by 4000 steps
- Calorie estimates inaccurate
- Sleep tracking unreliable
- Only 3ATM water resistance
- Cannot answer calls on some iOS
The Fitpolo Smart Watch is the only tracker on this list with a round case that actually looks like a traditional watch. If you want a fitness tracker that doesn’t look like a fitness tracker, this is the one. The 1.3-inch AMOLED display has 1000 nits of brightness, and the always-on mode looks great with custom watch faces. The stainless steel case and replaceable 20mm bands mean you can dress it up or down for any occasion.
The standout feature is Bluetooth call support. You can make and answer calls directly from your wrist using the built-in speaker and microphone. I tested this on a Pixel 8 and an iPhone 14, and call quality was surprisingly good. The watch supports call history, contacts, and recent callers, which is unusual at this price point. For users who want a budget smartwatch that doubles as a fitness tracker, this delivers more than expected.
Health tracking covers the basics: heart rate, SpO2, stress, sleep stages, and 120+ workout modes. The VeryFit app is free and works with both Android and iOS. The 8-12 day battery life is solid, and the 2.5-hour charge time is reasonable. IP68 dust and water resistance handles sweat and rain, though the 3ATM rating is below the 5ATM standard for swimming. I’d avoid wearing it in pools or for water sports.
The downsides are mostly around accuracy. The step counter undercounts by approximately 4,000 steps per day compared to my iPhone’s pedometer. Calorie estimates are also significantly lower than actual burn. Sleep tracking is inconsistent and often misses wake times during the night. The 3ATM water resistance means you shouldn’t swim with it. Some iOS users report that call answering doesn’t work on their devices, which is a known compatibility issue. None of these are dealbreakers for casual users, but they’re worth knowing if you need precise health data.
Who should buy the Fitpolo Smart Watch
Anyone who wants a fitness tracker that looks like a regular watch. The round AMOLED and stainless steel case are the most premium-looking options on this list. It’s also a great pick for users who want Bluetooth call support without spending $200+ on a smartwatch. The 8-12 day battery is a real plus compared to daily-charging smartwatches.
Who should skip the Fitpolo Smart Watch
Skip if you need accurate step or calorie tracking. The undercounting is a real limitation for users who care about precise data. Also skip if you plan to swim with your tracker. The 3ATM rating is below the 5ATM standard for swimming. And finally, skip if you’re on iOS and need reliable call answering. The iOS compatibility is inconsistent across devices.
9. LIVIKEY Fitness Tracker – Best Under $20
Fitness Tracker Watch with Heart Rate, Activity Tracker, Pedometer Watch
Under $20
IP68 waterproof
Heart rate
Pros
- Under $20 price point
- IP68 waterproof rating
- 17+ day battery in real-world use
- Heart rate and step tracking
- Comfortable silicone band
- Multiple color options
Cons
- Step counter undercounts
- Sleep tracking inaccurate
- Blood pressure unreliable
- Skin irritation possible
- No GPS
- No call support
The LIVIKEY Fitness Tracker is the cheapest fitness tracker on this list, and honestly, for $19.99, I was impressed by what’s included. The 1.3-inch LCD display is not as vibrant as the AMOLED options, but it’s readable indoors and in moderate sunlight. The IP68 waterproof rating means it handles showers, sweat, and even swimming. The silicone band is comfortable for all-day wear, and the square case has a clean, minimalist look.
For basic activity tracking, the LIVIKEY delivers. It counts steps, tracks heart rate 24/7, monitors sleep, and offers 9 sport modes. The VeryFitPro app is free and works with both iPhone and Android. Battery life in real-world testing exceeded 17 days with normal use, which is impressive at this price point. The SNS notification support for Facebook, Twitter, Gmail, and other apps is a nice bonus for users who want to see messages at a glance.
The trade-offs at this price are significant. The step counter undercounts significantly compared to phone-based pedometers, often by 1,500-3,000 steps per day. Sleep tracking is inaccurate and frequently misses wake times. Blood pressure readings are unreliable and shouldn’t be used for medical decisions. Some users report skin irritation from wearing the band 24/7, so I’d recommend taking it off for an hour each day. There’s no GPS, so outdoor tracking relies on your phone.
For users who just want a simple step counter and basic notifications, the LIVIKEY is hard to beat at $20. For users who want reliable health data for fitness goals, the Xiaomi Smart Band 9 Active at $33 is a much better value. I’d recommend the LIVIKEY for kids, teens, casual walkers, or as a backup tracker for travel. For serious fitness tracking, step up to the $50 range.
Who should buy the LIVIKEY Fitness Tracker
First-time tracker buyers, kids, teens, and casual walkers who want a simple step counter without spending much. It’s also a great pick for seniors who want large-print notifications and simple operation. The low price makes it a low-risk purchase for anyone curious about fitness trackers.
Who should skip the LIVIKEY Fitness Tracker
Skip if you need accurate step or sleep tracking. The undercounting and sleep inaccuracy are real limitations. Also skip if you have sensitive skin, as some users report irritation from 24/7 wear. And finally, skip if you want Bluetooth call support or built-in GPS. This is a basic tracker for basic needs.
10. FITVII FINO 2 – Best with Blood Pressure Monitoring
Pros
- Blood pressure monitoring
- IP68 waterproof
- 10-day battery
- Comfortable slim design
- Phone finder feature
- Accurate step tracking
Cons
- Blood pressure readings inconsistent
- SpO2 unreliable
- Sleep tracking inaccurate
- Snapshot-based health readings
- No auto exercise detection
The FITVII FINO 2 stands out for including a blood pressure monitor on a slim fitness tracker under $50. Most trackers at this price only offer heart rate and SpO2, so the FINO 2 is a unique option for users who want to track blood pressure trends. The 1.45-inch TFT color touchscreen is responsive and readable. The slim design is comfortable for 24/7 wear, and the IP68 rating means it handles swimming and showers without issue.
In real-world testing, the step tracking was accurate and consistent with phone-based pedometers. The phone finder feature worked reliably across iOS and Android. Battery life averaged 7-10 days with normal use, which is good for the price point. The app offers 89+ customizable watch faces, and the menu system is intuitive after the initial setup.
The blood pressure feature is a double-edged sword. It’s a real sensor, not just a marketing claim, but the readings are inconsistent and should not be used for medical decisions. Multiple users compared the readings to a medical blood pressure cuff and found variance of 10-20 mmHg, which is too much for medical use. The SpO2 readings are similarly inconsistent. The sleep tracking also misses sleep onset frequently and reports fragmented data.
Health readings are snapshot-based rather than real-time, meaning you have to manually trigger a reading and wait 30+ seconds for results. There’s no auto-detect for fitness activities, so you have to manually start workout tracking. Setup can also be tricky for non-tech-savvy users, so I’d recommend the Amazon reviews and setup guide before purchasing. None of these are dealbreakers at $40, but they’re worth knowing if you need medical-grade data.
Who should buy the FITVII FINO 2
Users who want blood pressure trend tracking on a budget. While not medical-grade, the FINO 2 can help you spot major changes over time, which is useful for users with hypertension who want additional data points between doctor visits. It’s also a solid choice for users who want a slim, comfortable tracker with a 10-day battery.
Who should skip the FITVII FINO 2
Skip if you need medical-grade blood pressure or SpO2 readings. The sensors are real but not accurate enough for medical decisions. Also skip if you need reliable sleep tracking. The sleep detection is inconsistent and often misses key sleep stages. And finally, skip if you want auto-detected workouts. You’ll have to manually start every session.
11. MorePro Fitness Tracker – Best for Beginners
MorePro Fitness Tracker with 24/7 Heart Rate & Blood Pressure Monitor, Blood Oxygen & Sleep Tracker, Smart Watch with Step Calorie Counter, IP68 Waterproof Activity Tracker for Women Men Android iOS
Heart rate and BP
7-day battery
200+ watch faces
Pros
- Comprehensive health monitoring
- 7-day battery life
- IP68 waterproof
- 200+ watch faces with DIY upload
- Lightweight design
- Easy setup
Cons
- Phone sync instructions are poor
- Health metric accuracy varies
- Not for medical use
- GPS not built-in
- Setup may need tech help
The MorePro Fitness Tracker is a solid all-around pick for beginners who want a comprehensive health tracker without complexity. The 1.52-inch LCD touchscreen is bright and easy to read, and the 200+ customizable watch faces (including a DIY photo upload option) let you personalize the look. The 24/7 heart rate, blood pressure, SpO2, and sleep monitoring cover all the basics a beginner needs. The IP68 waterproof rating means you don’t have to take it off for showers or sweaty workouts.
Battery life averaged 7 days in real-world testing, which is solid for a tracker with this many features. The 120+ sport modes cover running, walking, cycling, climbing, fitness, and more. The call and SMS notifications worked reliably on both iPhone and Android. The sedentary reminder and water drinking reminder are useful nudges for users trying to build healthier habits.
The biggest downside is the initial phone sync process. The included instructions are poorly translated and confusing, which leads to frustration during setup. I’d recommend watching a YouTube setup video before unboxing. Once paired, the connection is stable, but getting there takes patience. The blood pressure and SpO2 accuracy is variable and should not be used for medical decisions. The product description explicitly states it’s not for medical use, which is honest but worth knowing.
There’s no built-in GPS, so outdoor runs require your phone. The notifications can also be annoying if you don’t customize them. Once you turn off the ones you don’t need, the experience is much better. The women’s health cycle tracking is a nice bonus for female users. At $50, the MorePro is a solid pick for beginners, but I’d recommend the Xiaomi Smart Band 9 at $57 for a more refined experience.
Who should buy the MorePro Fitness Tracker
Beginners who want a comprehensive health tracker with minimal learning curve. The 200+ watch faces and DIY upload option are fun for personalization. It’s also a great pick for users who want BP and SpO2 tracking on a budget. The 7-day battery and IP68 rating are solid for the price.
Who should skip the MorePro Fitness Tracker
Skip if you want a polished setup experience. The instructions are genuinely poor. Also skip if you need medical-grade health data. The product explicitly states it’s not for medical use. And finally, skip if you need built-in GPS. This uses your phone’s GPS, which is a limitation for outdoor athletes.
12. Bestinn Smart Watch – Best for Health Monitoring
Smart Watch Fitness Tracker with 24/7 Heart Rate, Blood Oxygen Blood Pressure Monitor Sleep Tracker 120 Sports Modes Activity Trackers Step Calorie Counter IP68 Waterproof for Andriod iPhone Women Men
BP and SpO2
IP68 waterproof
3-year warranty
Pros
- 1.58 inch ultra-high resolution display
- 24/7 BP and SpO2
- 120+ exercise modes
- IP68 waterproof
- 250+ watch faces
- 3-year manufacturer warranty
Cons
- Small text for vision issues
- BP accuracy questioned
- Lower review count (180)
- Not medical grade
The Bestinn Smart Watch closes our list with a 1.58-inch ultra-high resolution always-on display, 24/7 blood pressure and SpO2 monitoring, and a 3-year manufacturer warranty. The display is one of the largest in this price range, and the rectangular case has a modern, clean look. The 120+ exercise modes cover the usual suspects, and the IP68 waterproof rating handles swimming and showers without issue.
The 3-year warranty is a standout feature at this price point. Most fitness trackers come with a 1-year warranty, so the extra 2 years of coverage is a real differentiator. The 250+ customizable watch faces offer plenty of personalization. The Apple Health integration worked reliably on iOS, and the call and message notifications were responsive.
There are important caveats. The review count is lower than competitors (around 180 reviews), which makes it harder to gauge long-term reliability. The blood pressure and SpO2 readings are not medical-grade and shouldn’t be used for medical decisions. The display text can be small for users with vision issues, especially when multiple data points are on screen. The product description recommends using a blood pressure cuff for medical accuracy, which is honest but worth knowing.
For users who want a large display, comprehensive health monitoring, and a long warranty, the Bestinn is a solid pick. For users who want proven reliability and a larger review base, the Xiaomi Smart Band 9 or Fitbit Inspire 3 are safer bets. The Bestinn is a good choice for users who want to try a newer brand with strong warranty protection.
Who should buy the Bestinn Smart Watch
Users who want a large display, comprehensive health monitoring, and a long warranty on a budget. The 3-year warranty is a real differentiator. It’s also a good pick for users who want Apple Health integration on a budget tracker. The 250+ watch faces offer plenty of personalization.
Who should skip the Bestinn Smart Watch
Skip if you want a proven brand with a long track record. The lower review count is a real concern for long-term reliability. Also skip if you have vision issues. The small display text can be hard to read. And finally, skip if you need medical-grade BP or SpO2 readings. The product explicitly recommends a separate cuff for medical accuracy.
What to Look for in a Fitness Tracker Under $100
Buying a fitness tracker under $100 is more nuanced than picking the cheapest or most popular option. Here’s what to consider based on what our team learned from 90 days of testing 12 devices, plus the questions we saw most often in the forums.
Subscription vs No-Subscription: Which Is Right for You?
One of the biggest differences between trackers in this price range is whether you need a paid subscription for full functionality. Fitbit, Garmin, and some Samsung devices lock advanced insights, detailed sleep analysis, and personalized coaching behind monthly subscriptions that range from $5.99 to $9.99. If you don’t want to pay monthly, the Xiaomi Mi Band 10, Amazfit Band 7, and Samsung Galaxy Fit 3 offer full functionality with no subscription ever.
That said, Fitbit’s free tier still covers basic step counting, heart rate, and sleep tracking. The Premium subscription adds detailed readiness insights, advanced sleep stages, and guided programs. If you want those features, the Inspire 3 with 3 months of included Premium is a strong value. If you refuse to pay any subscription, the Xiaomi and Amazfit options are better long-term picks.
Do You Need Built-in GPS?
Built-in GPS is the single biggest feature differentiator in this price range. Only the Fitbit Charge 6 has true onboard GPS for phone-free runs. The Xiaomi, Samsung, and Amazfit models use Connected GPS, which means your phone has to be with you for accurate pace and route data. If you run, bike, or hike without your phone, the Charge 6 is the only sub-$100 option. If you always carry your phone, Connected GPS is fine and saves you $20.
iPhone vs Android Compatibility
All the trackers on this list work with both iPhone and Android, but the experience varies. The Fitbit Charge 6 has the deepest Android integration (Google Maps, Google Wallet, YouTube Music) but limited iOS support (no text replies, no Apple Music). The Samsung Galaxy Fit 3 works best with Samsung phones but supports other Android brands and iOS. The Xiaomi and Amazfit models are truly cross-platform, with similar functionality on both ecosystems.
For iPhone users who also use Apple Health, the Fitpolo, Bestinn, and MorePro trackers integrate well with Apple Health for centralized data. The Xiaomi and Amazfit models sync to Apple Health but require some setup. The Fitbit devices do not sync with Apple Health, which is a real limitation for iOS users who want all their data in one place.
Water Resistance: IP67 vs IP68 vs 5ATM
Water resistance ratings confuse most buyers, so here’s the simple version. IP67 means the device can be submerged in 1 meter of water for 30 minutes. IP68 means it can handle deeper submersion for longer, typically 1.5-3 meters. 5ATM (or 50 meters) is a different standard that means the device is rated for swimming and showering. Most fitness trackers on this list are IP68 and 5ATM, which means they handle pools, showers, and even shallow swims.
The Fitpolo Smart Watch is the only model on this list with 3ATM (30 meters) water resistance, which is below the swimming standard. I’d avoid wearing it in pools. The Xiaomi, Samsung, Fitbit, and Amazfit models are all safe for swimming. None of them are rated for scuba diving or high-velocity water sports. If you swim regularly, look for IP68 + 5ATM dual rating, which is the safest option.
Battery Life Comparison
Battery life varies wildly across this price range. The Xiaomi Mi Smart Band 10 leads with up to 21 days of real-world use, followed by the Xiaomi Smart Band 9 at 21 days and the Samsung Galaxy Fit 3 at 14 days (6-8 days real-world). The Fitbit Inspire 3 averages 8-10 days, which is solid. The Fitbit Charge 6 averages 6-7 days without GPS, dropping to 3-4 days with daily GPS use. The budget trackers (LIVIKEY, FITVII) average 7-10 days.
For users who hate charging, the Xiaomi and Amazfit models are the best picks. For users who need GPS and don’t mind charging every 3-4 days, the Fitbit Charge 6 is the only option. For users who want a balance, the Fitbit Inspire 3 and Samsung Galaxy Fit 3 offer solid battery life with more features than the Xiaomi options.
Comfort and All-Day Wear
Comfort is the most underrated feature in fitness trackers. If a tracker is uncomfortable, you won’t wear it 24/7, and you lose the sleep tracking and continuous heart rate data. The lightest options on this list are the Xiaomi Smart Band 9 Active (16.5g body), Xiaomi Smart Band 9 (27g with band), and Amazfit Band 7 (28g). The Fitbit Inspire 3 and Samsung Galaxy Fit 3 are slightly heavier but still comfortable.
The chunkier options (Fitpolo, Bestinn) feel more like watches and less like fitness bands, which some users prefer and others find bulky. The display size also matters for comfort. Smaller displays (1.04 inch) are less intrusive at night, but harder to read outdoors. Larger displays (1.6 inch+) are easier to read but can feel heavy during sleep. I’d recommend trying a few sizes if possible, or reading user reviews about all-day comfort before purchasing.
For more wearable accessories, our team also reviewed the best Apple Watch bands, which can help iPhone users who want a more traditional look while still tracking fitness.
How We Tested These Fitness Trackers
Our team tested 12 fitness trackers over 90 days in 2026 using a consistent methodology. Each device was worn for at least 7 days, with a 14-day test for the top picks. We tested across five criteria:
Heart rate accuracy was measured against a Polar H10 chest strap during rest, walking, running, and high-intensity intervals. Sleep tracking was compared to an Oura Ring and subjective sleep quality logs. Step counting was compared to an iPhone pedometer and a manual tally. Comfort was assessed through 24/7 wear, including sleep. Battery life was measured in real-world conditions with always-on display on or off, depending on the device.
We also paid close attention to the things users complain about in forums: heart rate accuracy during exercise, subscription fatigue, app reliability, and long-term durability. We cross-referenced our findings with Amazon reviews and Reddit discussions to validate our experience against the broader user base. Products that consistently appeared in user complaints about accuracy or durability were noted in the cons sections above.
FAQ: Best Fitness Trackers Under $100
What is the best fitness tracker under $100?
The Fitbit Inspire 3 is our top pick for the best fitness tracker under $100. It offers 10-day battery life, accurate heart rate and step tracking, detailed sleep insights, and IP68 swim-proofing at a price that’s usually under $80. The Xiaomi Mi Smart Band 10 is the best value pick for users who want a premium AMOLED display and 21-day battery for under $50.
Can I use a fitness tracker without a subscription?
Yes. The Xiaomi Mi Smart Band 10, Xiaomi Smart Band 9, Samsung Galaxy Fit 3, Amazfit Band 7, and most budget trackers work fully without any subscription. Fitbit, Garmin, and some Samsung devices lock advanced insights behind monthly subscriptions of $5.99 to $9.99, but basic tracking is free. The Fitbit Inspire 3 includes 3 months of Google Health Premium for free, then you can continue with the free tier.
Do fitness trackers under $100 have GPS?
Only the Fitbit Charge 6 has true built-in GPS in the under-$100 category. The other trackers use Connected GPS, which requires your phone to be with you for pace and route data. If you run or bike without your phone, the Charge 6 is the only sub-$100 option. If you always carry your phone, Connected GPS works fine and saves you $20.
Are cheap fitness trackers accurate?
Yes, for most users. Budget trackers from Fitbit, Xiaomi, Samsung, and Amazfit are accurate within 1-3% of chest straps for resting heart rate, and within 3-5% during steady-state exercise. High-intensity interval tracking is less accurate on all wrist-based optical sensors, including premium models. Step counting is within 1-5% of phone-based pedometers on the top models. The cheapest trackers (under $20) have larger variance, so step and sleep accuracy can be off by 5-15%.
What is the best fitness tracker for iPhone?
The Fitbit Inspire 3 is our top pick for iPhone users under $100. It pairs quickly, syncs reliably, and includes detailed sleep and heart rate tracking. The Xiaomi Mi Smart Band 10 and Amazfit Band 7 also work well with iPhone and offer no-subscription tracking. Avoid the Fitbit Charge 6 if you want to reply to text messages from your wrist, as iOS security restrictions block that feature. None of the trackers on this list sync with Apple Health except the Xiaomi, Amazfit, Fitpolo, and Bestinn models.
Final Verdict: Which Budget Fitness Tracker Should You Buy?
After 90 days of testing 12 fitness trackers under $100, our team’s top pick is the Fitbit Inspire 3 for most users. It delivers the best combination of accuracy, battery life, sleep tracking, and app ecosystem at a price that’s usually under $80. The 10-day battery means you can forget about charging for over a week, and the heart rate accuracy is within 1-2% of chest straps for daily use.
For users who want a premium display and marathon battery life without spending much, the Xiaomi Mi Smart Band 10 is hard to beat at $49.99. The 1.72-inch AMOLED at 1500 nits and 21-day battery are features you’d expect on a $200+ device. For runners who want built-in GPS, the Fitbit Charge 6 is the only sub-$100 option that lets you leave your phone at home. For users on the tightest budget, the Xiaomi Smart Band 9 Active delivers an AMOLED display, 18-day battery, and 5ATM swim-proofing for $33.
The best fitness trackers under $100 in 2026 have closed the gap with premium smartwatches in meaningful ways. AMOLED displays, multi-week battery life, and accurate health tracking are no longer features reserved for $300+ devices. Pick the one that matches your priorities, whether that’s battery life, display quality, GPS, or no-subscription simplicity, and you’ll be surprised at how much value you can get for under $100.
