Meet the BodyEcho: a sleep tracking headband that pairs with your smartphone to track how well you sleep. Designed by OxiRate, the device uses advanced sensors to track sleep stages, sleeping position, changes in blood oxygen saturation, heart rate, snoring, and more. You can use the companion app or web portal to make better sense of the data. All you need to do is put the BodyEcho on, set the smartphone app to Sleep Mode, and let it do the rest. You can support it on Kickstarter.
