When it comes to sleep tracking, you won’t find anything that compares to the accuracy of our app. Firstly, the app is powered SleepScore, featuring technology that uses sonar as a way to measure your breathing rate and body movement to accurately determine your path through the sleep stages. Secondly, it uses the speaker and microphone from your smartphone to measure your sleep, so there’s no need for stand-alone hardware like a mattress strip or wearable fitness tracker. Thirdly, it sits on your bedside table, so it’s completely non-contact! Finally, its accuracy is far superior to other non-contact sleep tracking apps. The app is based on best in-class algorithms that that have been validated against Polysomnography (PSG) and Actigraphy, the two clinically accepted standards of measuring sleep, with these results published in over 10 scientific peer-reviewed papers. The algorithms have been developed over 12 years with over 6 million nights of data.
