The Fitness Tracker Landscape
Fitness trackers have evolved from simple step counters to sophisticated health monitoring devices. Today's trackers measure heart rate, sleep quality, blood oxygen, and even stress levels. We've tested the leading fitness trackers to help you find the perfect companion for your health and fitness journey.
Best Overall: Fitbit Charge 6
The Fitbit Charge 6 continues Fitbit's legacy of accessible, feature-rich fitness tracking with improved accuracy and new Google integration.
Standout Features
- Most accurate heart rate tracking in class
- Built-in GPS
- Google Wallet and Maps integration
- 7-day battery life
- Comprehensive health metrics
The Charge 6 excels at the fundamentals. Heart rate tracking is noticeably more accurate during workouts compared to previous generations. The addition of Google services adds practical value, especially Google Maps turn-by-turn directions displayed on your wrist.
Sleep tracking remains industry-leading, providing detailed insights into sleep stages, restlessness, and recommendations for improvement. The Fitbit app's Premium membership ($10/month) unlocks advanced analytics, but the free features are substantial.
Premium Choice: Garmin Vivosmart 5
For serious athletes who want advanced metrics without smartwatch bulk, the Garmin Vivosmart 5 delivers professional-grade tracking in a compact form factor.
Advanced Metrics
- Body Battery energy monitoring
- Stress tracking with relaxation breathing
- All-day pulse oximetry
- Incident detection
- Training status and recovery time
Garmin's algorithms provide actionable insights that help optimize training. Body Battery accurately predicts when you're ready for intense workouts versus when you should rest. The Vivosmart 5 connects to Garmin Connect, arguably the best fitness app available with zero subscription fees.
Best Value: Xiaomi Mi Band 8
The Mi Band 8 proves you don't need to spend a fortune for effective fitness tracking. At a fraction of the cost of competitors, it covers all the basics remarkably well.
Incredible Value
- AMOLED display
- 16-day battery life
- 150+ workout modes
- Sleep and SpO2 monitoring

While technically a smartwatch, the Apple Watch SE serves as an excellent fitness tracker for iPhone users, offering seamless ecosystem integration.
iPhone Integration
- Automatic workout detection

The Activity Rings provide simple, effective motivation. The three rings (Move, Exercise, Stand) create psychological incentives that genuinely encourage more movement throughout the day. Apple Fitness+ ($10/month) offers studio-quality workout videos with real-time metrics integration.
Best for Sleep: Oura Ring Gen3
The Oura Ring takes a different approach, offering comprehensive health monitoring in ring form with particular excellence in sleep tracking.
Unique Advantages

The Oura Ring's sleep tracking is unmatched, providing detailed analysis of sleep stages, restfulness, and overnight heart rate variability. The Readiness Score uses sleep quality, recovery, and other factors to recommend whether to push hard or take it easy. The ring requires a $6/month membership after the first month.
Features to Consider
Heart Rate Monitoring
Continuous heart rate monitoring is now standard, but accuracy varies. Look for:
- Optical sensors with multiple LEDs
- Validated against chest strap monitors
- Real-time workout heart rate zones
- Resting heart rate trends
GPS Capabilities
Built-in GPS eliminates the need for a phone during runs:
- Independent tracking without phone
- Accurate distance and pace measurement
- Route mapping
- However, GPS significantly reduces battery life
Battery Life
Consider your charging tolerance:
- Basic trackers: 7-14 days typical
- GPS usage: dramatically reduces runtime
- AMOLED screens: shorter life than LCD
- Smart features: require more frequent charging
Water Resistance
Most trackers handle swimming:
- 5ATM (50m): Swimming and showering safe
- Lap counting in pool swim modes
- Open water swim tracking
- Water lock prevents accidental touches
App Ecosystem
The companion app can make or break the experience:
- Clean, intuitive interface
- Comprehensive data presentation
- Social features for motivation

Stress Monitoring
- Heart rate variability analysis
- Guided breathing exercises
- Stress score throughout day
- Recovery recommendations
Blood Oxygen (SpO2)

Making Your Choice
Consider these questions:
- What's your primary goal? General fitness, serious athletics, or health monitoring?
- What's your phone? iPhone users benefit from Apple Watch integration; Android users have more flexibility.
- What's your budget? Great options exist from $30 to $300+
