Powered by SleepScore™, the Sleep.com app uses sonar technology to track your sleep safely and accurately. Using your phone’s speakers and microphone, the app sends and receives sound waves that help us assess your sleep quality based on breathing and movement. We encounter sound waves in our everyday life simply by communicating with others, and the frequencies used in the Sleep.com app are well within the range considered safe.

Because the app’s sound frequencies are transferred through the air rather than applied directly to the body, our technology emits minimal energy. These energy levels fall within the acceptable range cited in numerous health guidelines and publications.
