First off , I went to the website to read up , Saw that one of my favorite guitarist had chimed in ( Vernon Ried) Wow , ok I though I would give the app a shot . Started it up , Hit Play then added the Campfire , the Night sounds , and the Sun mark ( Nature Sounds) and blended them soft . Turned down the volume on the Mac to soft sound and The stress just drifted right off . Make your own environment . Zone out . very cool Audio quality too.
