User Experience

This app is extremely simple to use from the moment you launch it until the moment you fall asleep. All you have to do is launch the app, choose what background music you want, and you're ready to start relaxing.

Features

This app works on the basis that when a person hears two different frequencies in his or her ears, they will in fact be heard in the brain as one frequency. Sounds are used in this app to help balance your nervous system as it enters the hypothalamus of your brain.

What this does is help to relieve any pressure on your sympathetic nervous system. The sounds can also help with relaxation, memory, and concentration. It is recommended that you try all of the sounds and settings in order to find the best one for you.
