Would you like to wake up with more energy?

It is a fact that the famous eight hours of sleep needed in an adult are just a myth, since they are not necessary if you know how to use 90-minute sleep cycles in your favor.

This application makes calculations and, once we indicate the time we want to wake up, it makes calculations backwards indicating the time to which it is better to go to bed and vice versa if you go to sleep at a certain time and you want to sleep only six hours (4 sleep cycles), that simple and useful.

A good rest requires 5-6 complete sleep cycles.
Sleeping in the dark and waking up with the sunlight helps to wake up with more energy.

A normal person falls asleep after 15 minutes in bed.
