Fitbit the Pedometer Is Getting Kicked Up a Notch with the the New

Fitbit
The pedometer is getting kicked up a notch with the new Fitbit device. The Fitbit is a $99 motion-detecting sensing device that can measure the user's activity even when asleep. It digitally records the distance a user walks or runs, right down to the number of steps, and calories burned. The device wirelessly sends data to its Web site, fitbit.com, giving users minute-by-minute details. Users can add consumption information at the Web site, allowing an accurate picture of calorie consumption and expenditures. Unlike other devices, like the Nike + iPod Sport Kit that monitors walking and running and sells for $29 or the Zeo Personal Sleep Coach that records brainwaves while the user is sleeping and sells for $399, the Fitbit combines both functions. The first-time Fitbit setup isn't very easy for users, but once over that hurdle, it's relative easy to use.
