One third of our lifetime is spent on sleeping and yet we seem to only pay attention to our daylight activities. But sleep is not isolated from our daylight activities: a good night sleep can assure you a better day. We therefore introduce Zento, a smart pillow with built-in sensors to track and help your sleep. Our Android app receives your sleep data via Bluetooth and analyzes them to figure out your sleep patterns. Zento can make your dream a bit sweeter.
