Get the new fitness tracker, UP by Jawbone

UP and UP24 use a precision motion sensor and powerful algorithms to passively track and quantify your steps, distance, calories, active time, and idle time. The UP app then calculates calories burned based on your age, gender, height and weight, along with activity intensity and duration. UP and UP24 use actigraphy to track your sleep, monitoring your micro movements to determine whether you are awake or asleep.
