What does the app do?

This app is a series of soundtracks to aid sleep. Each soundtrack has a lead-in male voice of gentle talking which aims to guide the user into a state of calmness and relaxation, and eventually sleep. The soundtracks comprise different frequencies creating a sensation that can soothe and calm the brain - the app developers describe this as "binaural beats that induce theta brainwaves". The app has 2 modules - Power Nap for a short, daytime snooze and Sleep, for longer, nighttime sleep. The user has the option of tailoring the various settings to their preferences such as the length of the track, turning of the lead-in voice, adjusting the volume of both the soundtrack and the voice, etc.

For the complete app description, go to either iTunes (apple) or Google Play (android).
