Free mobile app turns smartphone into non-contact sleep tracker

SleepScore Labs has released a mobile app that can turn any smartphone into a non-contact, standalone sleep tracker.
 
According to the California-based company, at least 1.2 billion people worldwide suffer from a variety of sleep issues, and nearly 60 per cent of all people misunderstand their own sleep problems due to a lack of measurable insights. Some use consumer sleep trackers, many of which require the purchase of wearable devices or other hardware and can be highly inaccurate.
 
SleepScore combines the convenience of a free standalone smartphone app with the verified accuracy of sleep-detecting sonar algorithms developed over the past 13 years by ResMed, a specialist in sleep medical devices, and tested and validated against polysomnography at accredited sleep labs worldwide.
 
SleepScore accesses a smartphone's microphones and speakers to detect users' sleep patterns without the need for obtrusive wearable devices or placing sensors under a pillow or mattress.
 
Using the smartphone's speakers, the app sends inaudible sound waves, which are reflected off the user's body and received back into the microphone. Algorithms then interpret the shape and movement of the reflected sound waves to sense full breathing waveform and body movements. The combination of these signals is used to decipher which sleep stage the user is in (wake, light sleep, deep sleep or REM), as well as the number of times users wake up through the night and the time it takes to fall asleep.
 
"Sleep affects all facets of people's health, and yet there has been no easy way to accurately measure or track it everywhere we sleep, until now," said Colin Lawlor, CEO of SleepScore Labs. "We've been developing this technology longer than the iPhone has existed. We're excited that, for the first time, virtually everyone can get a truer picture of their sleep health for free and make smarter decisions about how to get a more restful night's sleep."
 
Each morning, users receive a 1 to 100 score of how they slept, with an easy-to-read breakdown of what affected their scores, such as sleep length, time to fall asleep or interruptions. Users can view their SleepScores for the past seven days.
 
Users can select a sleep goal, such as "Sleep longer" or "Wake up less," then receive advice and simple challenges to help achieve their goals. After seven recorded nights, SleepScore will suggest if users should move on to a different goal.
 
A smart alarm wakes the user up at the ideal moment in their sleep cycle, within a timeframe they select.
 
Based on users' data, SleepScore will recommend evaluated products and services from its selected partners that could improve the quality of their sleep, ranging from innovative pillows to sound machines and snoring products.
 
A paid version of the app provides users with their complete sleep history, trend and correlations analytics, exportable data, and a sleep report for their doctor to view and discuss clinical sleep recommendations, if needed.
 
The app is free to download and use for iOS from the Apple App Store, with Android estimated to follow before the end of June from Google Play.
 
SleepScore Labs is a joint venture between ResMed, Dr Mehmet Oz and Pegasus Capital Advisors. It was created in 2016 and is headquartered in Carlsbad, California, with an office in Dublin, Ireland.
