This app requires the purchase of a Fitbit writs band. The band syncs with your phone. The app provides a broad array of exercise related activities including steps, sleep, food logs, running and workouts. The app can track steps alone without the wristband.
Reviews: Typical of many of the motion tracking devices. Decision to purchase should be based on price and need.
