Amazing for beginners – Music Theory by Musicopoulos Review

A must have app if you don't know much music theory The value is insane for beginners. I was looking everywhere for theory books and apps for piano and this was the only one I found. It has delivered ? However, I can see this app not being too helpful if you already took some music theory classes.
