The Jawbone UP wristband can track activity and log steps, calories burned, food intake and sleep. The UP series of activity trackers features a companion app, which is available for both iPhone and Android users.
Within the UP series, there are four different models of wristbands. Some of the higher-end models include advanced features such as a more accurate sleep tracking system and the ability to connect an American Express card to your wristband and use the tap-to-pay function. If style is important, the entry-level UP Move is the only one of the four to offer color choices beyond black and gray.
