C-System CBA Accordion Tutor App Reviews

I find this app to be handy for working out fingerings, chords and tunes. However, I do wish that it was more scalable to take better advantage of the larger surface area of the iPad. While it's listed as an iPhone app, I find that the keyboard is a bit too cramped on the iPhone. Also, it has a slight glitch in that certain chords will get stuck and keep playing, even when no longer touching the buttons.
