I made an app for melodic practice, exercise drills, memory training, experimentation etc

Excerpt from the original

Hi! I've released an Android app I made to help with music practice, and I thought people in here might get some use out of it. It's based around generating unique melodic phrases using a particular scale, and you can use those to create practice exercises or train yourself to repeat what you're hearing (what I mostly use it for), or just experiment with things like harmonisation or writing chord progressions under a melody. Or just take the music for whatever - some of the things it comes out with are pretty good!
