What is Sleep Theory?

Sleep Theory is a tool designed to eliminate sleep problems. This is a godsend for those people who cannot fall asleep for a long time, toss and turn at night and often wake up, and when they wake up in the morning they do not feel rested and full of energy – these and other situations are easily corrected with this application. But let’s take it in order, because the program provides its own means to solve each problem.

To quickly fall asleep, the program offers to use an extensive music library – the sound of rain, the roar of waves, the murmur of a stream, the crackle of a fire, ASMR sounds, and so on. Remember to activate the timer (from five minutes to two hours) so that the program will automatically turn off after the session ends.

It is known that sleep is cyclical, and it is easier and easier to wake up in the stage of REM sleep – in this case, a person feels alert and rested, ready for new deeds and achievements. Use an intelligent alarm clock that automatically tracks the phases and wakes the person exactly at the interval that falls on the fast stage.

Features:

  • “smart” alarm clock for quick and easy waking up;
  • library of quality sounds for falling asleep;
  • stylish widgets with useful information;
  • FM radio with themed audio content;
  • create a personal sleep schedule.

Use the Sleep Theory functionality every day, which helps the program collect statistics and, based on it, give the user tips and recommendations on improving the quality of sleep.
