PianoQuizz Взлом 3.2 + Чит Коды

PianoQuizz allows you to review intervals, scales and chords when you are away from your piano: on public transport, in a waiting room, in a boring meeting ;-)
This application will be useful for anyone working on improvisation.
For small iPhone screens that don’t allow you to view two octaves, you can slide the keyboard horizontally in order to reach the desired note.
