Fitbit One is Fitbit's 2nd generation activity tracker that replaced the Fitbit Ultra. In case you have not heard, the Fitbit is one (no pun intended) is of the most recognized activity trackers in the fitness industry. Fitbit has turned fitness into a lifestyle for those who have worn it, and the Fitbit One is for you. For starters, it never rests. During the day, it tracks your steps, distance, calories burned, and stairs climbed. Come nightfall, it measures your sleep cycle, helps you learn how to sleep better, and wakes you in the morning. The One motivates you to reach your goals by bringing greater fitness into your life seamlessly, socially, 24 hours a day.

    Sensors & Motors

    The One uses a MEMS 3-axis accelerometer that measures your motion patterns to determine your calories burned, distance traveled, steps taken, and sleep quality. Its altimeter also measures stairs climbed. The One also contains a cylindrical vibration motor, which allows it to vibrate when alarms are set to go off.

Syncing occurs automatically any time the One is within about 20 feet of the wireless USB dongle and is relatively motionless. The dongle plugs into your Mac or PC's USB port. Syncing and uploading require use of the Fitbit uploader application.
