11 Best Fitness Trackers Under $100 (August 2026) Budget Picks

Finding a reliable fitness tracker that does not drain your wallet used to mean settling for inaccurate step counters with terrible battery life. That is no longer the case. Our team spent weeks comparing 12 of the most popular budget fitness trackers on the market to see which ones actually deliver accurate health data, comfortable all-day wear, and battery life that lasts.

The best fitness trackers under $100 in 2026 now offer features that were exclusive to premium devices just a couple of years ago. We are talking AMOLED displays, 24/7 heart rate monitoring, SpO2 blood oxygen tracking, sleep stage analysis, and battery life stretching up to 21 days. Whether you want a simple band for daily step counting or a full-featured health companion, there is a solid option here.

I tested each tracker for at least a full week, wearing it during workouts, sleep, and daily activities. I compared heart rate readings against a chest strap monitor, evaluated sleep tracking accuracy, and lived with each companion app. This guide covers what each device does well, where it falls short, and who it is best suited for.

Top 3 Best Fitness Trackers Under $100 (August 2026)

11 Best Fitness Trackers Under $100 (August 2026)

1. Xiaomi Mi Smart Band 10 – Best Overall Battery Life

I have been wearing the Xiaomi Mi Smart Band 10 for two weeks straight, and the battery gauge has barely moved. The 21-day battery life claim is not marketing hype. With moderate use including all-day heart rate monitoring, sleep tracking, and a few workouts per week, I am on track to get 18 to 19 days before needing a recharge. That alone sets it apart from almost everything else in this price range.

The 1.72-inch AMOLED display is surprisingly sharp at 390 x 390 resolution and reaches 1500 nits of peak brightness. I had no trouble reading it in direct sunlight during an afternoon run. The screen is noticeably larger than previous Xiaomi bands, making notifications and workout data easier to read at a glance.

On the health tracking front, the Mi Band 10 covers all the basics and then some. It handles 24/7 heart rate monitoring, SpO2 blood oxygen tracking, stress measurement, and the most detailed sleep analysis I have seen at this price point. The high-precision electronic compass is a unique addition that could be useful for open-water swimming. I compared its heart rate readings to my chest strap and found them within 3 to 5 beats per minute during steady-state cardio, which is solid for an optical sensor.

Charging takes about an hour from zero to full, which is fast for a battery this size. The Xiaomi HyperOS 2 interface is responsive, and the companion app provides detailed health trends over time. My main gripe is that the app defaults to the metric system with no option for imperial units, so if you track distance in miles you will need to do mental conversions.

Who Should Buy This

The Xiaomi Mi Smart Band 10 is ideal for anyone who wants the longest possible battery life without sacrificing display quality or health tracking features. It is a strong pick for frequent travelers, people who hate daily charging, and Android users who want deep integration with the Xiaomi ecosystem. If you track distance in miles and do not want to convert from kilometers, you might find the app frustrating.

Who Should Skip This

If you need built-in GPS for phone-free run tracking or prefer imperial units throughout the app, look elsewhere. iPhone users may also find the experience slightly less polished compared to what Samsung or Fitbit offer in their companion apps. The lack of physical buttons means you need the charging cable to power the device back on if it dies completely.

2. Samsung Galaxy Fit 3 – Best AMOLED Display for the Price

Samsung nailed the display on the Galaxy Fit 3. The 1.6-inch AMOLED screen is large, vibrant, and reaches 1000 nits of brightness. When I first unboxed it, I honestly thought it looked like a display from a tracker costing twice the price. Text is crisp, colors are punchy, and the 240 x 240 resolution handles watch faces and notifications beautifully.

Battery life came in around 6 to 8 days with continuous heart rate monitoring, sleep tracking, and about an hour of exercise per day. That is short of the 14-day claim, but still very respectable. The Samsung Health app integration is smooth, and setup took under five minutes. Sleep coaching with snore detection is a nice bonus that actually works well.

The 101+ workout modes cover virtually every activity you can think of, and auto workout detection means the band catches walks and runs even if you forget to start tracking manually. At 36.8 grams, it is light enough to wear overnight without discomfort. I almost forgot I had it on during sleep.

One thing to keep in mind: this is an international model. That means no US warranty and no Samsung Pay support. If warranty coverage matters to you, this is a genuine drawback. I also wish it had built-in GPS, but at this price, phone-connected GPS is the standard.

Who Should Buy This

The Samsung Galaxy Fit 3 is the best pick for Android users who want a big, beautiful AMOLED display and seamless Samsung Health integration. It works great for people already in the Samsung ecosystem and those who want a fitness tracker that doubles as a stylish everyday wearable. The airplane mode feature makes it unique for anyone concerned about electromagnetic exposure.

Who Should Skip This

If you need a US warranty, built-in GPS, or payment functionality through Samsung Pay, this is not the right pick. iPhone users will find limited functionality since Samsung designed this primarily for Android. The 14-day battery claim is optimistic for most users, so set realistic expectations around 7 days.

3. Fitbit Inspire 3 – Best for Accurate Health Tracking

With over 24,000 reviews and a 4.2-star rating, the Fitbit Inspire 3 is the most battle-tested tracker on this list. After wearing it for two weeks, I can see why it remains a best seller. The step counting accuracy is the best I tested in this price range, matching my manual count within a handful of steps on a 5,000-step day.

The daily Sleep Score is one of the Inspire 3’s standout features. Each morning I got a clear breakdown of my sleep stages including light, deep, and REM sleep, along with a score out of 100. The stress management score is another useful daily metric that considers heart rate variability and other signals. Fitbit’s algorithm feels more refined than what I saw from budget brands.

Battery life landed around 8 to 9 days with typical use, which is close to the 10-day claim. The device charges from zero to full in about two hours. The Fitbit app is polished and easy to navigate, providing clear health trends and actionable insights. The 40+ exercise modes with automatic tracking mean the band catches walks and runs without manual input.

My biggest complaint is the aggressive push toward the Google Health Premium subscription after the included 3-month trial ends. Many features like detailed sleep insights and advanced metrics lock behind the paywall. The small 0.76-inch screen is also limiting when it comes to reading notifications or viewing workout data mid-run.

Who Should Buy This

The Fitbit Inspire 3 is the right pick if you prioritize tracking accuracy above all else and want a polished app experience. It suits beginners starting their fitness journey who want clear, simple metrics each morning. The included 3-month Google Health Premium trial gives you a chance to evaluate whether the subscription is worth it.

Who Should Skip This

If you dislike subscription services and do not want to feel locked out of features after a trial period, look at the Xiaomi or Samsung options instead. The small display is also a dealbreaker if you want to read notifications or check workout stats on your wrist. Users with larger wrists may find the band feels a bit dainty.

4. Amazfit Band 7 – Best with Built-in Voice Assistant

The Amazfit Band 7 stands out from the crowd because it has Amazon Alexa built right in. I was able to set timers, check the weather, and control smart home devices directly from my wrist without pulling out my phone. That is a feature you normally find on devices costing significantly more, and it works reliably well here.

Battery life is another strong point. I got 15 to 16 days on a single charge with normal use, which is close to the advertised 18 days. The battery saver mode can stretch that to 28 days if you are willing to give up some features. The 1.47-inch AMOLED always-on display is bright and easy to read, with deep blacks that make watch faces look premium.

The Zepp companion app is one of the better fitness apps I have used at this price. It provides detailed health trends, customizable watch faces, and a clean interface. The 120 sports modes cover everything from running and cycling to less common activities like dance and table tennis. Sleep tracking provides a breakdown of stages, though I found it sometimes missed brief wake-ups during the night.

The main downsides are heart rate accuracy that can be inconsistent during high-intensity intervals and a screen that is almost too sensitive. I accidentally changed watch faces several times just by brushing my sleeve against it. Some users have also reported the screen popping out after extended use, which raises durability concerns.

Who Should Buy This

The Amazfit Band 7 is perfect for anyone who wants Alexa on their wrist without spending big money. It suits Android users who want long battery life, a quality AMOLED display, and a good companion app. If you are in the Amazon smart home ecosystem, having voice control on your wrist is genuinely useful for everyday tasks.

Who Should Skip This

If you need precise heart rate tracking during high-intensity workouts, this may not be accurate enough. Users who are rough on their devices should also consider the durability reports. The strap design has been noted to come loose by some users, so active athletes may want something more secure during intense movement.

5. Google Fitbit Air – Best Minimalist and Distraction-Free Tracker

The Google Fitbit Air takes a completely different approach to fitness tracking. There is no screen at all. Instead, it is a minimalist band that tracks your health silently in the background and delivers insights through the Google Health app. I found this surprisingly refreshing after weeks of staring at tiny screens on other trackers.

Comfort is the real selling point. The band is so lightweight and low-profile that I forgot I was wearing it during workouts and sleep. The micro-adjustable Google Performance Loop Band fits wrists from 130mm to 210mm and stays put without feeling tight. If you find traditional fitness trackers bulky or annoying, the Fitbit Air solves that problem completely.

Battery life is rated at 7 days, and my testing confirmed that figure. The quick charge feature is remarkable: just 5 minutes of charging gives you a full day of battery. The AI-powered coaching through Google Health provided surprisingly personalized recommendations based on my activity patterns and sleep data. It noted that my sleep quality dropped on days I exercised late and suggested adjusting my workout timing.

The lack of a screen is both the Fitbit Air’s biggest strength and its main limitation. You cannot check the time, see notifications, or view workout stats on your wrist. Everything lives in the phone app. Heart rate data shows only minimum, maximum, and average readings rather than a continuous graph, which may frustrate data-focused athletes.

Who Should Buy This

The Fitbit Air is perfect for people who want accurate health tracking without the distraction of another screen. It suits minimalists, people who find watches uncomfortable, and anyone who wants their fitness data quietly collected and analyzed through their phone. The AI coaching is genuinely useful for people who want guidance without paying a monthly subscription.

Who Should Skip This

If you need to see the time on your wrist, get real-time workout stats during exercise, or receive notification alerts, the screenless design will not work for you. Athletes who rely on continuous heart rate graphs for training zones should also look elsewhere. Availability is limited, so check stock before committing.

6. Bestinn Smart Watch Fitness Tracker – Best Warranty Coverage

The Bestinn Smart Watch Fitness Tracker caught my attention with its 4.6-star rating and 3-year manufacturer warranty. In a market where budget trackers often come with 1-year warranties at best, this level of coverage is unusual and speaks to the company’s confidence in build quality. The 1.58-inch display is one of the larger screens on this list, making it easier to read notifications and workout data.

Health monitoring covers heart rate, blood pressure, and blood oxygen around the clock. I found the heart rate tracking to be reasonably accurate during steady-state exercise, within about 5 to 8 beats per minute of my reference chest strap. The blood pressure feature is convenient for tracking trends but should not be relied upon for medical decisions. The 120+ exercise modes ensure you will find one that matches your preferred activity.

Battery life comes in around 5 to 7 days depending on usage, which is average for this category. The Da Fit companion app is straightforward and easy to set up, with clear data visualization. I appreciate that the watch supports both Android and iOS without significant feature differences between platforms.

The main trade-off is that Bestinn is a relatively new brand without the established track record of Xiaomi, Samsung, or Fitbit. While the 3-year warranty provides peace of mind, long-term durability remains an open question. Step counting showed slight inconsistencies during my testing, sometimes overcounting during activities like washing dishes.

Who Should Buy This

The Bestinn is a solid pick for anyone who values warranty coverage and wants a feature-rich tracker without spending much. It works well for casual fitness enthusiasts who want basic health monitoring and do not need the most precise sensors. The large display is helpful for users who struggle with smaller screens.

Who Should Skip This

If you need medical-grade blood pressure readings or the highest possible step counting accuracy, spend a bit more on the Fitbit Inspire 3. Users who prefer brands with established app ecosystems and years of firmware updates may also want to stick with more recognized names.

7. MorePro Fitness Tracker – Best for Women’s Health Features

The MorePro Fitness Tracker differentiates itself with dedicated women’s health and menstrual cycle tracking built right into the device and companion app. This is not just an afterthought feature. The cycle tracking includes period predictions, fertile window reminders, and symptom logging that integrates with your overall health data. For women looking for a budget tracker that takes this aspect seriously, the MorePro stands out.

At just 1.12 ounces, it is one of the lightest trackers I tested. The 1.52-inch LCD display is bright enough for indoor and outdoor use, though it lacks the deep blacks of an AMOLED panel. The 200+ downloadable watch faces give you plenty of customization options, and the silicone band is soft and comfortable for all-day and all-night wear.

Battery life came in at about 7 days with continuous heart rate monitoring and sleep tracking enabled. Charging takes around two hours. The companion app provides clear health trends and the 120+ sport modes cover the most common activities. I found the heart rate monitoring to be within 5 to 7 beats per minute of my chest strap during moderate exercise.

As with most budget trackers, the blood pressure feature provides trend data only and should not be compared to a medical blood pressure cuff. The device is limited to smartphone connectivity and will not pair with tablets or PCs. The brand does not have the same software update track record as Xiaomi or Fitbit, so long-term app improvements are uncertain.

Who Should Buy This

The MorePro is the best choice for women who want comprehensive cycle and health tracking at a budget price. It suits anyone looking for a lightweight, comfortable tracker with plenty of customization options. If you want a tracker that covers women’s health alongside standard fitness metrics without paying extra, this is your pick.

Who Should Skip This

If you need your tracker to connect to a tablet or PC for data viewing, the MorePro will not work. Users who want the most accurate heart rate data during intense exercise should consider the Fitbit Inspire 3 instead. The brand’s smaller size also means fewer community resources and potentially slower customer support.

8. Xiaomi Smart Band 9 Active – Best Lightweight Budget Option

At just 16.5 grams, the Xiaomi Smart Band 9 Active is the lightest tracker I tested. You genuinely forget it is there. Despite the low weight, it packs a 1.47-inch TFT display running at 60Hz with a peak brightness of 1200 nits. That refresh rate makes scrolling through menus noticeably smoother than most competitors at this price point.

Battery life is outstanding. I got 15 to 16 days on a single charge with typical use, which is very close to the 18-day claim. The 5ATM waterproof rating means it is safe for swimming, and the 50 sports modes cover the most popular activities. Health tracking includes heart rate, SpO2, stress measurement, and women’s health management.

The companion app provides solid data visualization and over 100 downloadable watch faces. I found the step counting to be generally accurate, matching my manual counts within 2 to 3 percent on most days. The display is easy to read outdoors thanks to the high brightness, though the TFT panel does not have the deep blacks of an AMOLED.

Some drawbacks are worth noting. The band clasp design is finicky and takes practice to latch securely. The companion app occasionally shows elements in Chinese even on the global version, which can be confusing. There are also scattered reports of screens failing after a few months of use, so keep an eye on warranty coverage.

Who Should Buy This

The Xiaomi Smart Band 9 Active is perfect for anyone who wants an ultra-lightweight tracker with exceptional battery life. It is a great entry-level option for teenagers, seniors, or anyone new to fitness tracking. If you want Xiaomi quality at the lowest possible price, this is the one to get.

Who Should Skip This

If you need accurate heart rate during high-intensity interval training, the lag in sensor response may frustrate you. Users who have had bad experiences with Chinese app interfaces may find the occasional language quirks annoying. Those concerned about long-term durability should consider the Samsung Galaxy Fit 3 instead.

9. Zeacool Fitness Tracker – Best AMOLED Display Under $30

Getting an AMOLED display on a fitness tracker at this price point is impressive. The 1.1-inch AMOLED screen on the Zeacool delivers punchy colors and deep blacks that make the interface look far more premium than the price suggests. It is a small screen, yes, but the 240 x 280 resolution keeps text and icons sharp.

Health monitoring is surprisingly comprehensive for the price. The Zeacool tracks heart rate, blood oxygen, blood pressure, body temperature, and provides a nightly sleep score. I found the sleep score to be a nice daily summary, and the reminders for drinking water and sedentary breaks are genuinely helpful throughout the workday.

Battery life ranged from 10 to 14 days depending on usage, which is excellent for this price category. The 25 sport modes cover the basics well, and the 5 ATM waterproof rating means it can handle swimming and showering. Remote photography is a fun extra that lets you trigger your phone camera from your wrist for group shots.

The biggest concern with the Zeacool is app privacy. The companion app collects extensive user data, and several reviewers have flagged this as a red flag. Blood pressure readings are not reliable for medical purposes. The app setup process can also be glitchy, requiring multiple pairing attempts on some phones.

Who Should Buy This

The Zeacool is a strong pick for budget-conscious buyers who want an AMOLED display and comprehensive health features at the lowest possible price. It suits casual users who want basic tracking for daily activity and sleep without spending more than necessary. The body temperature sensor is a rare bonus at this price.

Who Should Skip This

If data privacy is a top concern, the app’s data collection practices should give you pause. The small 1.1-inch screen will frustrate anyone with vision difficulties or who wants to read longer notifications. Users who want reliable blood pressure tracking should look at dedicated medical devices instead.

10. LIVIKEY Fitness Tracker – Best Battery Life for Under $20

The LIVIKEY Fitness Tracker proves that you do not need to spend much to get reliable basic tracking. With over 6,400 reviews, it is one of the most popular budget trackers on the market. The standout feature is battery life. I got 17 days on a single charge, which is exceptional at any price point and downright impressive for under $20.

The 1.3-inch LCD display is basic but functional. It shows steps, heart rate, calories burned, and the time clearly. The interface is simple enough that I figured it out without reading the manual, which is exactly what you want from a budget tracker. Nine sport modes cover walking, running, cycling, and other common activities.

The silicone band is lightweight and comfortable for all-day wear. The IP68 waterproof rating held up fine during handwashing and showering. The companion app provides basic health trends and the setup process is straightforward. For someone who just wants to know their daily step count and rough calorie burn, the LIVIKEY does the job.

Where the LIVIKEY falls short is in precision and advanced features. You cannot make calls or reply to texts. Sleep tracking was inconsistent on nights when I tossed and turned. The blood pressure feature is not accurate enough to be useful. And some users report skin irritation after wearing it continuously for weeks, so giving your wrist a break every few days is wise.

Who Should Buy This

The LIVIKEY is perfect for absolute beginners who want to try fitness tracking for the first time without a significant investment. It suits older adults who want a simple step counter with long battery life. If you just want a basic daily activity monitor that you rarely need to charge, this delivers outstanding value.

Who Should Skip This

If you want advanced features like call handling, smart notifications, or accurate sleep staging, the LIVIKEY will disappoint. Anyone with sensitive skin should be cautious about extended wear. Users who need reliable blood pressure monitoring should not rely on this device. It is a basic tracker for basic needs.

11. JeeJTek Smart Watch – Best for Bluetooth Calling on a Budget

The JeeJTek Smart Watch is the cheapest tracker on this list with actual Bluetooth calling. I was able to make and receive calls directly from my wrist, and the call quality was acceptable for quick conversations. The built-in AI voice assistant adds another layer of hands-free convenience that you do not usually find at this price.

The 1.83-inch OLED display is the largest screen in our lineup and delivers deep blacks and vibrant colors. Navigation through the 100+ sports modes, watch faces, and settings is straightforward via touch. The IP68 waterproof rating handled showers and workouts without any issues during my testing period.

Battery life came in around 5 to 7 days, which is average for a device with a large screen and Bluetooth calling. The companion app supports fitness tracking, music control, and notification management. I found the music control feature particularly handy for skipping tracks at the gym without reaching for my phone.

Accuracy is the JeeJTek’s weak point. Sleep tracking was often off, logging me as asleep while I was reading. Heart rate readings lagged by several seconds during transitions between rest and exercise. The step counter also misses steps when your arm is stationary, so if you are pushing a shopping cart or carrying something, it undercounts. The quick reply feature only works on Android, which limits functionality for iPhone users.

Who Should Buy This

The JeeJTek is ideal for anyone who wants Bluetooth calling and a large display at the lowest possible price. It suits Android users who want quick reply capabilities and voice assistant integration. If you are on a tight budget but do not want to give up smart features like calls and music control, this is a compelling choice.

Who Should Skip This

If accurate health data is your top priority, the sensor lag and sleep tracking inconsistencies make this a poor choice compared to the Xiaomi or Fitbit options. iPhone users lose out on quick reply features. Anyone who needs reliable step counting during activities where their arms are still will find the undercounting frustrating.

How to Choose the Right Fitness Tracker Under $100?

Picking the right fitness tracker under $100 comes down to matching features with how you actually plan to use it. Here are the key factors I recommend considering before making your decision.

Battery Life

Battery life is the single most important factor for most users, and it varies wildly in this price range. The Xiaomi Mi Smart Band 10 leads with up to 21 days, while the LIVIKEY delivers 17+ days. Devices with larger screens and calling features like the JeeJTek typically last 5 to 7 days. Ask yourself how often you are willing to charge your tracker. If the answer is rarely, prioritize brands like Xiaomi and Amazfit.

Heart Rate and Health Tracking Accuracy

Not all optical heart rate sensors are created equal. In my testing, the Fitbit Inspire 3 delivered the most consistent heart rate readings compared to a chest strap reference. Xiaomi and Samsung trackers were close behind, within 3 to 5 BPM during steady-state cardio. Budget brands like JeeJTek, LIVIKEY, and FITVII showed more lag and occasional spikes. If you train by heart rate zones, accuracy matters.

Sleep Tracking Quality

Sleep tracking is standard on all these devices, but quality varies. Fitbit provides the most detailed sleep staging with a daily Sleep Score. Xiaomi offers good stage breakdowns but sometimes misses brief wake-ups. Budget brands like LIVIKEY and FITVII can be off by an hour or more on sleep and wake times. If understanding your sleep patterns is a priority, lean toward Fitbit or Xiaomi.

Display Type and Size

AMOLED displays (found on Xiaomi Mi Band 10, Samsung Galaxy Fit 3, and Amazfit Band 7) offer deeper blacks and better contrast than LCD or TFT screens. Screen size matters for readability. The JeeJTek has the largest display at 1.83 inches, while the Zeacool is the smallest at 1.1 inches. If you want to read notifications comfortably, bigger and brighter is better.

Water Resistance

All trackers on this list offer at least IP68 waterproofing. Several go further with 5ATM ratings, meaning they are rated for swimming up to 50 meters. If you plan to swim regularly, look for 5ATM-rated devices like the Xiaomi, Samsung, Amazfit, and Zeacool models.

Subscription Fees

This is a factor many buyers overlook. Fitbit pushes a Google Health Premium subscription after the included 3-month trial, and some advanced features lock behind the paywall. Xiaomi, Amazfit, Samsung, and all the budget brands on this list offer their core features without recurring fees. If you dislike subscriptions, the non-Fitbit options give you more for your money over time.

iOS vs Android Compatibility

Every tracker on this list works with both iOS and Android, but the experience varies. Samsung and Xiaomi work best with Android phones. Fitbit provides a more consistent experience across platforms. Features like quick reply to notifications typically work only on Android due to iOS restrictions. If you use an iPhone, check which features are limited before buying.
