The Fitbit Tracker’s super-sensitive 3D motion sensor tracks how active you are, on average, on any given day. It uploads the data through a wireless base to the website, and organizes the information into pie charts and bar graphs tracked over time to give you an idea of your fitness level—steps you take, calories you burn, even showing you how active you are throughout a day.
Slip the Tracker into the Fitbit sleep wristband, and it will keep a watchful eye as you sleep. When your info uploads to Fitbit. com, you’ll see not only how long, but also how well, you slept. It monitors how many times and how long you wake up during the night
The Fitbit Tracker is light and small enough to wear all day without anyone noticing it. Tuck it in your pocket or clip it to your belt
