• See all your activity stats in one place with a daily dashboard that shows your steps, calories burned, sleep, heart rate and more.
• Designed to be water-resistant to 50m, Fitbit Charge 4 automatically tracks swim workouts and can be worn in the shower, pool and beyond.
• Amp up your workout when you control music, like songs and browse recent playlists and podcasts from Charge 4.
• Fitbit Charge 4 makes it easier to see your stats in sunlight, at night or any time, thanks to a large touchscreen and backlit display that adjusts to different lighting conditions.
