Binaural by Sonalkiss is the first app available on the AppStore that allows users to fully control every aspect of their binaural experience. This app is one of the only apps that utilizes realtime sine-wave generation which, in turn, allows the user to customize everything from the frequency to the specific binaural offset of their chosen tones. Additionally, the app allows the user to choose solfeggio tones from the Pythagorean skein and uses a unique UI experience that allows for easy navigation through this matrix of solfeggio tones.
