is an activity-tracking app that you can use either in conjunction with one of Fitbit's wearable bands or on its own to keep updated on how active you are each day. The app takes notes of your steps, distance traveled, calories burned, sleeping patterns, weight gain or loss, heart rate, food intake, hydration, and more. The app is great for fitness enthusiasts who want to workout smart, and it enhances your activity by not only tracking your progress but also with voice cues, music control, and GPS connectivity.
Fitbit is also compatible with iPhone touch using iOS 8.0 and later.
