Benefits of using a sleep tracker and sleep cycle alarm clock
With modern day work schedules our sleep patterns have become widely irregular and oftentimes much shorter than they should be. PrimeNap Sleep Tracker can help you analyze your sleeping patterns and correct them if necessary. Using PrimeNap's smart alarm functionality you can avoid being pulled out of deep sleep by a well-meaning time-based alarm clock and instead wake up gently after sleep cycle completion and thereby simulate a natural awakening.


How it works: Movement during sleep is known to roughly correlate with the actual sleep stages obtained by polysomniography. This sleep movement is registered by the phone and translated into fairly accurate sleep cycle information.

Recommended use: Use this sleep app with proper hardware. If convenient switch on airplane/flight mode to minimize any emissions. Reboot or close other apps that might cause the phone to heat up during the night.
