This device automatically tracks your daily movements and sleep cycles to help determine if you are getting enough exercise and sleep. Similar to NASA technology that monitors astronauts in space, the device's integrated accelerometer monitors the intensity and duration of movements, tracks steps taken and distance traveled, and calculates calories burned--even during activities that do not require walking. The sensor fits into the included wristband while you sleep and tracks tiny tremors in the wrist to determine how long it took you to fall asleep, how often you woke up, and how long you were actually asleep, not just lying in bed. When the device is within 4.5 m of the USB charging station, it automatically uploads information to the manufacturer's website, where your readings are displayed on timelines and graphs. About the size of a USB flash drive, the wellness tracker clips to a belt or fits in a pocket. Includes software compatible with Windows 7, Vista, XP, and Mac for uploading readings to the website. Operates for 10 days after a 1 1/2-hour charge via USB. 6 L x 1 W x 1 cm D. (28 g)
