If there's one thing I've learned after three years of literary preparation, it's that the key is sleep! The key to success, of course, but also the key to the mind, health and even self-esteem!
That's why an app that allows you to keep control of your sleep seems amazing to me!
The concept is very simple: sometimes you're overwhelmed with work and you stay up late. Other times, you relax and party with your friends without thinking about going to bed.
