Fitbit adds Bluetooth to its new activity monitors

Fitbit helped popularize the market for small devices you carry around with you to measure your steps, calories burned, distance covered, and other daily activities. Now it’s unveiled two new Fitbit devices that add Bluetooth, so you can wirelessly sync your activity measurements to an iPhone, iPad, and soon to Android smartphones and tablets.

The $60 Fitbit Zip contains a small screen that displays your basic activity measurements, while the $100 Fitbit One adds an altimeter, accelerometer and ability to monitor your sleep patterns.

Both devices integrate with the Fitbit mobile app for logging activity data, food intake and weight, and for showing progress towards personal goals. Users can also transmit data to a Mac or PC through a Bluetooth dongle.
