It all starts with your 6-month Premium membership* and 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 the 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 ECG (Electrocardiogram) App -Keep track of your heart health with a compatible ECG app that assesses your heart for atrial fibrillation—a heart rhythm irregularity—and share the results with your doctor (coming Soon)
EDA (Electrodermal Activity) Scan App - Use the on-wrist EDA Scan app to detect electrodermal activity—tiny changes in your skin's sweat level which may indicate your body's response to stress.
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.
Reflections - Easily log your mood in the app from Very Stressed to Very Calm and observe changes over time.
Oxygen Saturation (SpO2) Monitoring - Track SpO2—the level of oxygen in your blood—to help you learn when there may be an indication of important changes in your overall wellness.
Heart Rate Variability - Understand if your body is showing potential signs of stress, illness, or fatigue based on your past month’s trends in the variation of time between each heartbeat—known as heart rate variability.
Breathing Rate - Get to know your average breaths per minute and see if there are any sudden increases that could indicate a change in your well-being with a view of your breathing rate trends from the past month.
Skin Temperature Tracking - Track your skin temperature variation each night so you can be aware of potential signs of changes in your body like fever or ovulation.
Sleep Score & Sleep Stages - Get a better understanding of your sleep quality with a daily Sleep Score and graphs of your time in light, deep, and REM sleep.
