It lets you see how many steps you have taken and the amount of calories your body is burning. The Edge is waterproof to 50 meters. You can wear the device on your wrist but may also clip it to your waist during your activity.
The Edge detects sleep mode and tracks the number of hours you have slept and sleep efficiency levels.
