OVERVIEW:
Heart rate tracking: The heart of it all—heart rate powers important data like calorie burn, sleep stages, resting heart rate & more.
Active Zone Minutes: Tracks your time in heart rate zones so you get credit when you work harder. Workouts in cardio or peak zones earn double minutes.
Built-in GPS: See pace & distance on your wrist—no phone needed.
Cardio Fitness Score: Estimate your fitness level using your VO2 Max (how well your body uses oxygen during exercise).
Daily Readiness...
Battery life of 6+ days. Battery life and charge cycles vary with use, settings and other factors; actual results will vary. We recommend charging your tracker every few days to ensure you are always tracking.
