EverSleep is a wearable, sleep-tracking device that tracks oxygen levels, snoring, and sleep patterns while you sleep. 20 million sleep trackers have been sold. Many of them indicate wearers sleep poorly -- NONE of them identify sleep apnea (marked by drops in blood oxygen levels). EverSleep monitors oxygenation of the blood. Blood oxygenation drops (desaturates) with sleep apnea. EverSleep detects these drops so that wearers know if they should pursue medical intervention. Our device utilizes medical grade technology.
