Health o Meter announced on Tuesday the launch of its new Nuyu line of health tracking devices and an associated mobile app. The system relies equally on the Nuyu Activity Monitor, which tracks steps, calories, distance and sleep; and connects with its counterpart Nuyu app via Bluetooth. The $48 Monitor can be worn on the wrist (with one of 8 available strap colors) or belt -- even tied to shoelaces. It displays your constantly-updated stats on a large OLED screen which is depth rated to 30 meters and runs for up to four months on a single battery. The app itself is free and available for both Android and iOS, though the data is only compatible with Apple's Health Kit.
