By tracking steps, distance and calories burned, the Fitbit One tracker lets you reach your health and fitness goals. This clever gadget syncs automatically to your computer or Bluetooth® compatible smartphone, allowing you to upload stats and track your progress with detailed charts and graphs. At the online Fitbit site you can compare your data with friends and family and even provide an encouraging message to spur them on.
Fitbit also allows you to measure your sleep cycle and find out how long you've slept, how many times you woke and the overall quality of your sleep. Fitbit's compact design can be attached to a belt, placed in a pocket or clipped to a wrist strap.
