The concept, preset programs, available tones, and other auditory elements are excellent. The UI is busy for some, with fonts too small to read without glasses. The real challenge is lack of scrolling shortcuts for the built in options and worse, for my music library - took me 3 minutes to get to songs starting with Ss.
The training itself was effective, using both sleep and caffaine.
Suggest leveraging apples apis for the music library. That might have added bonus of being able to select a playlist, album, or artist.
