Nightware,is a digital therapeutic that uses an Apple Watch and an Apple iPhone that are configured and logged into a software application and the Nightware server. Throughout the night, Apple Watch sensors monitor body movement and heart rate during sleep. These data are sent to the Nightware server and, using a proprietary algorithm, the device creates a unique sleep profile for the wearer. When Nightware detects that a wearer is experiencing a nightmare, the device provides vibrations through the Apple Watch. Nightware is available by prescription only and is intended for home use.We have a clinical trial underway including a virtual trial in which anyone living in the US can enroll.
