What Common Both Can Do?
- Continuous heart rate tracking: Both devices continuously monitor heart rate throughout the day and night using optical sensors. This allows consistent tracking of resting heart rate trends and supports deeper insights into overall fitness and recovery.
- PurePulse HR technology: Both models use Fitbit’s PurePulse heart rate system, which enables continuous HR tracking without a chest strap. This technology is central to sleep analysis, calorie estimation, and activity intensity measurement.
- Step tracking: Each tracker records daily steps automatically. This helps users measure daily movement and progress toward activity goals without manual input.
- Distance tracking: Both devices estimate distance traveled using step count and stride length. This allows users to track walking and running distance even without GPS.
- Calories burned tracking: Both models calculate estimated calories burned based on heart rate, activity level, and personal profile data. This is useful for weight management and energy balance tracking.
- Automatic activity recognition: Each tracker can automatically detect common activities like walking and running. This ensures workouts are logged even if users forget to start a session manually.
- Sleep tracking: Both devices monitor sleep duration automatically when worn overnight. This enables users to understand total sleep time and sleep consistency.
- Sleep stage tracking: Using heart rate data, both models break sleep into stages such as light, deep, and REM sleep. This provides deeper insight into sleep quality beyond total hours slept.
- Silent vibrating alarms: Both trackers include vibration-based alarms that wake users quietly. This feature is useful for alarms and reminders without disturbing others.
- Smartphone notifications: Both devices can display notifications from a connected smartphone. This allows users to stay informed without constantly checking their phone.

- Touch/tap interaction: Both trackers rely on touch or tap-based interaction rather than full physical buttons. This keeps the design minimal while allowing basic navigation.
- Fitbit app compatibility: Both devices sync with the Fitbit mobile app for data analysis and long-term tracking. The app provides dashboards, trends, and historical insights for health metrics.
- Wireless syncing: Each tracker uses Bluetooth to sync data with smartphones. This allows automatic background syncing without cables.
- Water resistance: Both models are designed to handle sweat, rain, and light splashes. This makes them suitable for everyday wear but not for dedicated swimming sessions.
- Multi-day battery life: Both trackers support multiple days of use on a single charge. This reduces charging frequency and improves everyday usability.
