The Fitbit tracker is an advanced pedometer that promises to track, in addition to number of steps taken and distance traveled, the calories burned and even the amount of sleep you got. The wait for Fitbit, which has been under development and eagerly anticipated for about a year, is finally over and units will soon begin shipping for advance orders. Using technology similar to that found in the Nintendo Wii, the Fitbit tracks motion in three dimensions and then silently uploads the information to Fitbit.com. The Fitbit looks like a small clip that can be attached to any article of clothing. A wireless base station is included that the Fitbit uploads to whenever it’s nearby. The price is $99, not much more than traditional electronic pedometers.
