The FitBit Tracker is a new device that can help you keep track of your fitness every day--even when you are asleep.

If you are always anxious to know whether you have done enough exercise and have burned enough calories for the day, the FitBit Tracker is a must-have item for you.

The FitBit Tracker has a motion sensor which records the number of steps you have taken while walking or running, keeping tabs on the calories burned all the while. Even when you are asleep, it measures and records all the movements you make while lying down, like tossing and turning.

FitBit Tracker can be comfortably worn all day, as it can be placed in your pocket, clipped to your clothing or worn on your wrist. It has a base station which can be connected to a computer for up-to-the-minute wireless synchronization.
