Fitbit Charge 5 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 Daily Readiness, 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. 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.
