How It Works
Do what's best for your body. Fitbit Charge 5 + Premium connects the dots between your activity, sleep and stress so you can make the best decisions for your body, mind and health. It all starts with your 6-month Premium membership1 and Daily Readiness2, a score based on activity, sleep and heart rate variability (HRV) that helps you optimize your workout routine. Your score comes with personalized activity recommendations: low means go easy and recover--light yoga, deep breathing--while a high score gives you the green light to go all out. Enhance your recovery routine with advanced stress-management tools like the on-wrist EDA sensor. Stay ahead of heart health with atrial fibrillation (AFib) heart rhythm assessments using the on-wrist ECG app.3 And you'll always have motivation to reach new goals with hundreds of guided workouts, a gallery of refreshing mindfulness sessions plus the fitness features you know and love like Active Zone Minutes and built-in GPS. Fitbit is part of the Google family.
Daily Readiness Score
Optimize your workout routine with a score that reveals if you're ready to exercise or should focus on recovery. You'll get a personalized activity goal for the day, plus recommended workouts or recovery sessions based on your score./²
Stress 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.
Take steps to improve your stress levels with an on-wrist EDA sensor mindfulness session. The app detects electrodermal activity--tiny changes in your skin's sweat level which may indicate your body's response to stress.
Fitbit ECG App & Irregular Heart Rhythm Notifications
There are two ways to uncover AFib, right at your fingertips. With the ECG app, you can take an assessment on demand. Plus, use irregular heart rhythm notifications to look for signs of AFib while you're still or sleeping.³
