How to Choose a Fitness Tracker
Battery life is king at this price point. The Amazfit Band 7 lasts up to 18 days and the Mi Band 8 lasts 16 days — that's 2+ weeks of forget-it-and-wear-it convenience. The Fitbit Inspire 3 at 10 days and MorePro at 5-7 days mean more frequent charging. If you hate charging devices, go Xiaomi or Amazfit.
App quality varies dramatically. Fitbit has the best app by far — intuitive, social, with challenges and community features. The Zepp app (Amazfit) and Mi Fitness app (Xiaomi) are functional but less polished. The MorePro app is bare-bones. If you care about data visualization and sharing your progress, Fitbit wins despite being $10 more.
Display tech matters for outdoor use. The Mi Band 8 and Amazfit Band 7 use AMOLED displays — the same tech in flagship smartphones. These are visible in direct sunlight and have deep blacks. The Fitbit Inspire 3 uses OLED (good but dimmer). The MorePro uses a basic LCD that's hard to read in bright sunlight.
What You Get at $50 vs $150+
- At $50 and under: Steps, heart rate, sleep, SpO2, basic notifications, 1-2 week battery, swim-proof
- At $150-300: Built-in GPS, ECG, blood pressure, voice assistants, mobile payments, app store, 1-2 day battery
- At $300+: LTE connectivity, advanced health sensors, large app ecosystem, premium build materials
For 80% of people who just want to track daily activity and sleep, a $30-50 fitness tracker does everything you need. The extra $100-250 for a smartwatch buys features most people don't use regularly.
Frequently Asked Questions
Are cheap fitness trackers accurate enough?
For step counting, yes — most budget fitness trackers are within 5-10% of research-grade pedometers. A 2023 accuracy study found that Xiaomi Mi Band and Fitbit Inspire both counted steps within 3-5% of actual steps on flat ground. Heart rate accuracy is more variable — expect ±5-10 BPM during steady-state exercise and ±15-20 BPM during high-intensity intervals. For sleep tracking, budget trackers correctly identify sleep vs wake about 85-90% of the time, but sleep stage breakdowns (REM, deep, light) are less reliable than clinical polysomnography.
Fitness tracker vs smartwatch — which should I get?
Get a fitness tracker if you mainly want step counting, heart rate, sleep tracking, and basic notifications — they're lighter, cheaper, and battery lasts 1-2 weeks. Get a smartwatch if you want GPS, app responses, music control, mobile payments, and a full color display. Smartwatches cost $150-400 and last 1-2 days per charge. Our guide covers fitness trackers under $50 — for smartwatch options, see our smartwatches guide.
Do fitness trackers work without a phone?
Yes for basic tracking — all four trackers in our guide record steps, heart rate, and sleep without a phone nearby. They store 7-14 days of data internally and sync when you're back in Bluetooth range. However, you need a phone for: initial setup, viewing detailed stats and history, GPS-connected running maps (all four rely on phone GPS), and receiving notifications. The Xiaomi Mi Band 8 and Amazfit Band 7 can store more offline data (7-14 days) than the MorePro (3-5 days).
Can I wear a fitness tracker while swimming?
All four trackers in our guide are water-resistant enough for swimming. The Xiaomi Mi Band 8 and Amazfit Band 7 are rated 5ATM (safe for pool swimming up to 50 meters depth). The Fitbit Inspire 3 is also 5ATM rated. The MorePro is IP68 rated (safe for submersion but not rated for swimming pressure). For regular pool swimming, the Mi Band 8 and Amazfit Band 7 are your best bets — they both track swim laps, stroke type, and SWOLF efficiency scores. Don't wear any budget tracker for scuba diving or high-impact water sports.
