How does the app use my phone’s speakers and microphone to track my sleep?
The app uses sonar technology to accurately track your sleep. Just like the echolocation that bats use to sense their surroundings at night, the app sends silent signals into your sleep environment. When these sound waves reflect into your microphone, our advanced algorithm interprets their shape and movement — determining your breathing rate, assessing your body movement, and turning those insights into an accurate record of your nightly sleep patterns.
