Small enough to fit in the palm of your hand, the Fitbit Ultra uses an OLED screen that's easy to read.

The Fitbit Ultra adds an altimeter to its accelerometer to measure activity. Though shaped like a clip itself, the device also comes with a belt holster.

The Fitbit Ultra's light 0.4 ounce weight is barely noticeable when clipped to the hip.

Very tiny, the Fitbit Ultra's small size makes this quarter seem massive.

The FitBit Ultra also is available in a plum-colored hue.

You connect and charge the Fitbit Ultra to PCs and Macs using its USB base station. The device can also wirelessly sync data when in a range of 15 feet.
