I enjoyed your write up, and was surprised to read that it was built in Godot, which I'd only ever considered for games, but of course it makes sense that games are simply a kind of app.
Love that you employ the circle of 5ths in the keyboard, whereas a more naive approach might've been to just ascend stepwise from C.
Any plans for an iOS version? Does Godot make it easy to port to other platforms?

Yes, there are plans for an iOS version! Godot has native support for iOS, so it should be pretty much plug-and-play. I haven't done it yet because of the developer fee that Apple charges, and because I am mainly an Android user myself. If there is enough interest though, I'm sure my partner would let me borrow her Macbook & iPad in order to bring this out though :)
App looks lovely
