The Wellness Monitor Wristband

The Fitbit wristband automatically tracks your daily movements and sleep cycles to help determine if you are getting enough exercise and sleep. As comfortable and unobtrusive as a gel wristband, the device contains an accelerometer that monitors the intensity and duration of movements, tracks steps taken, distance traveled, and calculates calories burned, as well as an altimeter that measures elevation. The Fitbit wristband tracks how long you took to fall asleep, how often you woke up, and how long you were actually asleep, not just lying in bed. The device automatically uploads the information to the manufacturer's website wirelessly via Bluetooth when it is within 15' of a paired iPad 3 or later, a notebook computer, or select smartphones (iPhone 4s or later, Samsung Galaxy SIII and Note 2). Data can also be synched into popular fitness apps such as SparkPeople and Lose It! Operates for up to 7 days after a 1 1/2-hour charge via USB. Black. 2" L x 3/4" W x 1/2" D. (1 oz.)
