A Good Start

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.

Waste of money

The app too full of flaws. Only a few notes are visible on the screen, not even 2 octaves are displayed. There’s no scrolling to compensate for that. No settings of any type, other than making the note labels visible or not.
I have the Hohner chromatic accordion app. That works fine, but it’s limited to iPads, so I thought this would be comparable on the iPhone. I was very wrong.
