Choosing the right fitness tracker can be overwhelming with so many options on the market. Whether you’re a casual fitness enthusiast or a serious athlete, there’s a tracker designed for your needs. We’ve tested and reviewed the top 5 fitness trackers of 2025 to help you make an informed decision.
OUR PICKS
1. Fitbit Charge 6
The Fitbit Charge 6 remains one of the most complete fitness band options in 2025. It features built-in GPS (so you can leave your phone behind on runs), ECG and AFib detection, continuous heart-rate and stress monitoring, and a bright color touchscreen. Reviewers say it offers “some of the best sleep-tracking we’ve tested.”
Pros:
- Lots of high-end sensors and wellness features in a band form factor
- Good ecosystem (app, data, insights)
- Excellent sleep tracking capabilities
Cons:
- Premium price for a fitness band
- Some of the best features locked behind a subscription (Fitbit Premium)
2. Xiaomi Smart Band 9
If you’re looking for value, the Smart Band 9 is among the best budget fitness trackers of 2025. It boasts a bright AMOLED screen, long battery life, and solid fitness tracking for the price. That said, it lacks built-in GPS (meaning you’ll need your phone for accurate route mapping) and the heart-rate/sensor accuracy isn’t quite on par with premium models.
Pros:
- Very good price-to-performance ratio
- Pleasant design and display for the cost
- Excellent battery life
Cons:
- No GPS onboard
- Slightly less accurate sensor performance than premium models
3. Oura Ring 4
If you’re less interested in “bands on your wrist during workouts” and more into seamless all-day wellness tracking, the Oura Ring 4 is compelling. It tracks 30+ biometrics, excels at sleep and recovery insights, and has a form-factor that many will prefer for comfort and wear-time.
Pros:
- Very subtle form-factor (ring) with strong sleep & recovery focus
- Excellent comfort and wearability around 24/7
- Comprehensive biometric tracking
Cons:
- Doesn’t give the same real-time workout feedback (compared to a wrist watch/band)
- Premium cost
4. WHOOP 5.0 One
For users focused seriously on training, performance, recovery and data-driven feedback rather than “just tracking steps,” the WHOOP 5.0 One is a standout. It’s built for athletes and those who want to dig into strain, recovery and readiness metrics.
Pros:
- Deep insights into fitness readiness, strain & recovery
- Excellent for people who treat training like a science
- Subscription-based with constant innovation
Cons:
- More expensive overall (often subscription required)
- Less “casual user” friendly — may over-deliver for someone just trying to walk more
5. Garmin vívoactive 6
While technically more smartwatch-hybrid than dumb tracker band, the vívoactive 6 offers one of the best all-around fitness/wearable packages in 2025: GPS, long battery life, good health metrics, plus sport-mode versatility. According to reviews, it blends “high-performance features” and suits most people.
Pros:
- Built-in GPS and robust multi-sport tracking
- Strong battery life and broad feature set
- Great balance between fitness tracking and smartwatch features
Cons:
- Price moves into “smartwatch” range rather than a simple tracker
- Might be more features than someone only casually tracking fitness needs
