Fitbit's trackers are the first all day activity trackers to offer Bluetooth Low Energy connectivity, so you see your stats in real-time.
Syncing occurs automatically any time the One™ is within about 20 feet of the wireless sync 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.
Syncing One™ to your smartphone or tablet requires Bluetooth Low Energy. This allows your One to sync wirelessly and automatically with a wide range of leading iOS and Android Smartphones.

If your phone does not support Bluetooth Low Energy, you're still in luck. The Fitbit mobile app works with all smartphones for logging data, receiving notifications, and viewing graphs and charts based on your last sync.
We recommend syncing your data regularly. As long as the One™ has minimum battery power, it tracks up to seven days of detailed, minute-by-minute data. For the preceding 23 days, it summarises your daily calories, distance, floors climbed, and steps taken.
The One™ battery indicator will appear when it's plugged into the charging cord. The battery lasts a minimum of ten days. You can charge it periodically with the provided battery charger, which plugs into your computer’s USB drive.

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.
The One™ is not waterproof. It shouldn't be worn while swimming. It is, however, rain, splash, and sweat-proof.
