It wakes you up after 3-minutes so you can fall asleep again and retrain your body. The device also has a power nap module to time your naps and wake you up exactly at the right time.
Thim emits a soft vibration each minute to track your sleep. The data is available on your iOS and Android devices. Expected to ship in 2017.[where to get it]
