Try Music Theory App for free and Tell me if it helps you
Hi everyone sorry for my english (Cuban), I used to feel music theory as a big mountain, so I decided 3 years to build an android music theory app that helps me with it, and not as a programmer but a musician, so you can take a look and see if it can help you. App name is PComposer in Google Play Store
