OVERVIEW:
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.*
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.*
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.* Get a read on your beat with up to 60% more accurate tracking during vigorous activities like HIIT, spinning and rowing.
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.*
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.*
All-day activity tracking: Just get moving; we’ll take care of the rest. Charge 6 tracks your steps, distance, calories burned & Active Zone Minutes 24/7.
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: Get instant access to tools that make your life easier—like a timer for interval training and a stopwatch for tracking sets at the gym.
