Exercise buddy: BodyMedia’s CORE armband is one-third smaller and slimmer than previous versions of this exercise and health tracking tool. The armband measures the number of steps you take, calories burned, skin temperature, and even your sleep duration and sleep efficiency. The LINK model connects over Bluetooth to the BodyMedia FIT app for Android and iOS. Both are available now, at $US180 for the CORE and $US250 for the LINK.
