How does the app compare to other sleep tracking apps?
The app is powered by SleepScore. SleepScore’s patented sonar technology uses echolocation to measure your movements and breathing throughout the night. The app’s proprietary ResMed algorithm analyzes that data, transforming it into an accurate, easy-to-understand view of your sleep quality. This algorithm leverages more than 12 years of research and 6 million recorded nights of sleep to provide consistently accurate sleep tracking — no wearable device required.

Most apps only measure your movement and are unable to assess your breathing rate. The app uses both movement and breathing to offer the most complete assessment of your sleep available outside of a sleep lab.
