According to Time, SleepHealth, a new iPhone app powered by IBM’s Watson intelligence system, is the latest app designed to help users understand how they sleep.
SleepHealth uses the sensors in your iPhone or Apple Watch to measure users’ movements throughout the night. It also uses the Apple Watch’s heart rate monitor to detect when the wearer has fallen asleep. The app then offers suggestions for living healthier and sleeping better.
SleepHealth includes a nap tracker and a personal sleep concierge, which were “designed specifically with the Apple Watch in mind,” according to IBM. When Apple’s next iPhone update launches, SleepHealth will reduce light exposure before sleep through Apple’s new Night Shift feature.
