Sensors
- Accelerometer
- Altimeter
The Fitbit Ultra uses a MEMS 3-axis accelerometer that measures your motion patterns to tell you your calories burned, steps taken, distance traveled, and sleep quality. A built-in MEMS altimeter measures your vertical climb up stairs and hills.
Colors
Fitbit Ultra comes in two color options:
- Blue
- Plum
The OLED display is blue on both models.

Wireless sync
The Fitbit Tracker syncs wirelessly to the base station (included in package) using an ultra-low power 2.4 GHz ANT radio transceiver.
Sync occurs automatically, anytime your Tracker is within about 15 feet of any base station and relatively motionless. The base station plugs into your Mac or PC’s USB port.
Syncing and uploading requires use of the Fitbit uploader application.
Memory
While we recommend you sync your data regularly, the Tracker can store up to seven days of detailed, minute-by-minute data, as long as it has minimum
battery power. It will also store daily totals (calories, distance, and steps) for the trailing 30 days, but without minute-by-minute stats.
Battery and power
The battery will last a minimum of 3 days between charges. The typical userâs experience is 5-7 days.
To check the battery level, place the Tracker on the base station and press the button. You can also see your battery level on your personal dashboard at Fitbit.com, based on the last time you synced wirelessly.
To charge the battery, just put it on the base station. It takes about an hour to fully recharge from a low indicator.
