First, this app has lessons that are incredibly well structured with you learning the lessons in a manageable size, and then going to exercises to test that knowledge. The only thing is, sometimes bugs impede progress on the final exams which doesn’t affect learning too much but makes it a little more difficult to track progression. It would also be good to be able to reset the exercises so that if you don’t perform well early on, you don’t need to get upwards of 200+ correct to get a higher grade on them. But the goal is to learn and as someone who has had a constant fear of music theory, this app is teaching me at a furious paceI’m adapting and learning various concepts including composition which is what got me interested in music theory in the first place. The exercises are locking in the knowledge gained and ensuring that it’s not lost the moment I close the app. I have noticed much greater understanding of musical structure when reading and creating music. I highly recommend it as a quality source of musical education, especially paired with an instrument and other sources!

Hello, thank you for this wonderful music theory app, I got to review a lot of comprehensive music theory concepts and do practices. I just want to notify you that after I update my iPhone to iOS 26, the comment function no longer works, and some pictures such as the Circle of Fifth picture in the Circle of Fifth section no longer shows up. Maybe the app will need to be updated to match the iOS system as well? Thank you!

I’ve been playing music a while, but was mostly self-taught so I had little knowledge of music theory. While it was hard to swallow my pride, I wanted to go back to the beginning and really try and learn and build my foundation from the ground up. for this being a free app, I have gotten so much more out of it than I expected and would highly recommend to anyone starting on a journey to learn music

This of a really great app got beginners of any instrument wanting to learn basic (and more complex) theoryThe format that the lessons and quizzes are provided in is very accessible and easy to use. The only thing I wish is that the app had more sections about more topics.
