Fitbit Charge 6

Heart rate on equipment
Connect Charge 6 to your favorite compatible exercise machine and see your real-time heart rate directly on the display.¹ Fitbit uses machine-learning to give you an even more precise read on key metrics like calories burned, sleep, Active Zone Minutes and your Daily Readiness Score.²

\n\n40+ exercise modes
With over 40 unique exercise modes, you can set personal goals and get key workout stats for everything from daily runs and bike rides to HIIT workouts, strength training and more.

\n\nActive Zone Minutes
Active Zone Minutes tracks the time you spend in your target heart rate zones, so when you work out harder, you get credit. Workouts in cardio or peak zones earn you double the minutes.

\n\nWorkout intensity map
After outdoor exercise with GPS, check your workout intensity map in the Fitbit mobile app to see your pace and heart rate zones throughout your route and learn where you put in the most effort. SmartTrack automatically recognizes and records workouts like elliptical, runs, swims and more.

\n\nECG
Keep track of your heart health with an ECG app³ that detects your heart’s rhythm and can notify you for signs of atrial fibrillation, or rhythm irregularities.

\n\nHealth metrics
Track SpO2—the level of oxygen in your blood—plus heart rate variability, breathing rate, skin temperature variation and resting heart rate, and know when your metrics move outside your baseline.⁴ A buzz on your wrist lets you know it’s time to move.

\n\nStress Management Score
Get a daily score showing your body’s physical response to stress. You can see how your exercise routine, mindfulness practice and sleep help to manage your stress levels.

\n\nSilent alarms and Smart Wake
Wake up to more peaceful mornings with a quiet vibrating alarm on your wrist and ready to take on the day with the Smart Wake alarm that goes off during your optimal stage of sleep—within 30 minutes before its set time.

\n\n7-day battery life
Don’t miss a beat with a battery that can keep your tracker going for up to 7 days, so you can leave your charger behind on your next long weekend trip.⁵

\n\n¹ Compatible with select workout machines that support the Bluetooth Heart Rate Profile, and coming soon to more. See here for more information on Charge 6-compatible machines.
\n² Daily Readiness Score requires a Fitbit Premium membership.
\n³ The Fitbit ECG app is only available in select countries. Not intended for use by people under 22 years old. See fitbit.com/ecg for additional details.
\n⁴ Not available in all countries. The SpO2 feature is not intended to diagnose or treat any medical condition or for any other medical purpose. It is intended to help you manage your well-being and keep track of your information. This feature requires more frequent charging.
\n⁵ Average battery life is approximate and is based on testing conducted in California in mid 2023 on pre-production hardware and software, using default settings with a median Fitbit user battery usage profile across a mix of talk, data, standby, and use of other features. Battery life depends on features enabled, usage, environment and many other factors. Use of certain features will decrease battery life. Actual battery life may be lower.
