Not feeling the watch-based movement and health trackers? Check out the Withings Smart Activity Tracker ($TBA). Able to slim into a pocket or into the included belt clip or arm band, it tracks heart rate, steps taken, strides run, distances covered, calories burned, and quality of sleep, all in a tiny 8 gram form factor. Other features include an OLED touchscreen display, a rear-mounted heart rate sensor, a two-week battery life, micro USB port for charging, and Bluetooth 4.0 for low-power wireless syncing to the Withings Health Mate App. Arriving Q1 2013.
