Fitness trackers bridge the gap between basic step counters and full smartwatches. They deliver meaningful health data — heart rate, sleep, GPS workouts — at a lower price and with longer battery life than a smartwatch. We compared five leading options across heart rate accuracy, GPS, sleep tracking, and battery life.

What to Look for in a Fitness Tracker
Heart rate accuracy
For resting heart rate and steady-state cardio, optical HR sensors are accurate within a few beats. During HIIT or activities with heavy wrist movement, accuracy drops on all optical sensors. For clinical-grade accuracy during intense training, pair your tracker with a chest strap. Garmin and Fitbit consistently outperform budget alternatives on optical HR accuracy.
GPS — built-in vs phone-connected
Built-in GPS lets you track routes without carrying your phone. It adds cost and reduces battery life. In 2026, the Fitbit Charge 6, Garmin Vivoactive 6, and Xiaomi Band 9 Pro all include built-in GPS at varying price points. If you always run with your phone, phone-connected GPS is adequate and more battery-efficient.
Sleep tracking quality
All five trackers here monitor sleep stages. Garmin's Body Battery synthesises sleep quality, HRV, and stress into a single readiness score. Whoop's Sleep Coach is the most actionable — it tells you exactly how much sleep you need based on your strain. Fitbit and Xiaomi provide solid sleep stage data in well-designed apps.
Battery life considerations
Seven days is the minimum worth considering for a daily fitness tracker — charging every few days disrupts continuous data collection. The Xiaomi Band 9 Pro (21 days) and Amazfit Band 7 (18 days) are standouts for battery. Using GPS drains battery faster on any device.
Our Verdict
The Fitbit Charge 6 is the best fitness tracker for most people — built-in GPS, ECG sensor, Google integration, and the clearest health app experience. For serious athletes who train by data, Whoop 5.0 provides unmatched recovery coaching with its new ECG sensor. Best value by a wide margin: Xiaomi Smart Band 9 Pro at €75 with 21-day battery and built-in GPS.
