Key Features

40+ 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.

Daily Readiness Score
Based on your stress, sleep and activity, your Daily Readiness Score helps you know what your body can handle so you can dial your workout plans up or down. Get daily activity recommendations based on your Daily Readiness.*
*Daily Readiness Score requires a Fitbit Premium membership. Premium content recommendations are not available in all locales and may be in English only.

24/7 heart rate
Watching your heart rate during exercise lets you know when you’re in fat burn, cardio or peak zones so you know how hard you’re working. The more you can comfortably push yourself, the more benefits you’ll see for your heart.

Active Zone Minutes
When you work out harder, you deserve more credit. Active Zone Minutes tracks the time you spend in your target heart rate zones, giving you double minutes when you’re in cardio or peak. We do the math and show you if you’re hitting the recommended 150 minutes each week.*
*Based on recommendations of the World Health Organization and American Heart Association.

Cardio fitness level
Get to know your VO2 max—a measurement of how well your body uses oxygen when you’re working your hardest. Keep tabs on your score to see how you improve over time.*
*Requires Fitbit mobile app.

Built-in GPS
See your pace and distance during outdoor workouts—no phone necessary—using built-in GPS, then see a map of your workout route in the Fitbit mobile app.

High & low heart rate notifications
Your heart says a lot about your body, so stay on top of it with alerts that let you know when your heart rate is above or below your average baseline.

Skin temperature tracking
Track your skin temperature nightly for variations from baseline that may be related to sleep environment, activity, menstrual cycle & more.*
*Requires Fitbit mobile app. Only displays temperature variation and not available in all countries. Not intended for medical purposes. Significant changes in ambient temperature may negatively impact skin temperature tracking.

Health 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.*
*Requires Fitbit mobile app. The Health Metrics dashboard and the metrics displayed in the dashboard are not available in all countries. This feature is not intended to diagnose or treat any medical condition and should not be relied on for any medical purposes. It is intended to provide information that can help you manage your well-being. If you have any concerns about your health, please talk to a healthcare provider.

Workout 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.

Timer & stopwatch

Our most accurate heart rate on a tracker yet
Your heart rate can tell you so much about your health and fitness, and Charge 6 features our most accurate heart rate on a tracker yet.* 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.**
*Compared to other Fitbit fitness trackers as of Fall 2023. Does not include Pixel or Fitbit smartwatches. Performance of heart rate tracking may be affected by physiology, location of device and your movements and activity.
**Daily Readiness Score requires a Fitbit Premium membership.

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

Water resistant
Charge 6 is water resistant up to 50 meters, which means you’re free to swim, sweat and more without worry.*
*Charge 6 is designed to comply with a water protection rating of 5 ATM under ISO standard 22810:2010 when manufactured, but it is not waterproof. Water resistance is not a permanent condition and decreases or is lost over time due to normal wear and tear, repair, disassembly or damage. Dropping your Charge 6 may result in loss of water resistance. Charge 6 is designed to be used in shallow water and should not be used for activities involving water at high velocity or high temperature. Some Charge 6 bands are not water resistant.

Notifications
Get notifications for calls, texts and smartphone apps like Google Calendar, Gmail and WhatsApp—plus send quick replies right from your wrist.*
*Your compatible phone must be in Bluetooth range of your Fitbit device to use this feature. Quick replies for Android users only. Fitbit Charge 6 works with most phones running Android 9.0 or newer or iOS 15 or newer and requires a Google Account and internet access. Some features require a Fitbit mobile app and/or a paid subscription. See Fitbit.com/devices for more information. Works with most phones running Android 9 or iOS 15 or newer.

7-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.*
*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 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.
