This iPhone App Can Measure The Quality Of Sleep
It Uses Ultrasound To Measure The Pattern Of Breathing And Movements While Sleeping
There are many apps and devices to monitor sleep. Some can even monitor REM, and deep sleep phases, but do not give a useful measure informing if the user slept well. There are also fitness trackers but are not specialized in something with the complexity of sleep tracking. This free iPhone app is more sophisticated than other sleep tracking app. It measures sleep by ‘pinging’ the sleeper overnight with an ultrasound, which allows it to detect movement and breathing patterns, similar to bats using echo-location. It detects the signature patterns of breathing and movement while sleeping, and shows a sleep score. Also, the sound waves have a frequency of 18KHz to 20KHz, having no impact on sleep.
