I use it every day, Its a good app and works well in most areas. It would be great if
- the note recognition would have an adjustable range. Its too simple. Needs more range.
- if in the key recognition area the key info (circle of fifth) could be switched off. Its too easy to count instead of look at the key signature
- interval recognition. Same as notes, needs more range. Add compound.
- chords, add chord inversions
- Ear Training / Intervals. Setup doesnt work. If I select for example P5 and P8 it also gives me TT ???
- Ear Training / Scales, would be great to play the scales
Implement all that, and yes, of course charge some extra $ for it, the app is great already and worth the money, extra functionality, some more cost is OK.
Definitely one of the best theory training apps out there.
