SleepScore uses sonar on your phone to show you how bad your sleep is

I had to take a home sleep study years ago that used a fair number of wires to determine I had apnea in the first place.

SleepScore, a company co-founded by CPAP manufacturer ResMed, just released a free phone app that measures your sleep through sound waves through the phone's speaker.

The app aims to help people potentially diagnose sleep problems from a bedside table, with no wrist sensors, bed sensors or extra bedside devices required.

SleepScore's phone app works much like its bedside gadget, SleepScore Max, does: It sends out inaudible sound waves (basically, sonar) to measure bodily movement overnight.

The app measures sleep duration, the time it takes you to fall asleep, light sleep, deep sleep, REM sleep and wake time -- much like many sleep tracking fitness bands including the Fitbit Versa.

It's sensitive enough to measure respiration and recognize REM (rapid eye movement) periods, according to SleepScore Labs CEO Colin Lawlor.
