Music was the air I breathed growing up in Iceland but learning music theory was always presented to me as a memorisation problem. Here are the terms but I never actually learned anything like that. What I have always needed is to see the thing! and so you can get it, test it out, with the beta-testflight link below if you want to try it out and send feedback. It is designed for ipads but it works to a large extent on iPhones as well

Feedback welcome — especially from anyone who's thought about music cognition or visual learning!
