The technology in the app harnesses the power of sonar to accurately track users as they move through different sleep stages. Sonar uses echo-location like what bats use to hunt at night. The bats make a noise and send sound waves into the environment around it. Those sound waves reflect off nearby objects, and some of them reflect back to the bats. Our app utilizes these same principles. The patented Sonar Technology uses your phone speakers as a way to send silent signals and those reflected waves are received back into the microphone.
The advanced algorithms in the app then interpret the shape and movement of the reflected waves to sense your breathing rate and body movement. The combination of these two signals is used to accurately decipher your movement through the various sleep stages at night.
