Very good BUT

This honestly is I would say the best music theory app out there I do with that between this app “Theory” and “Tenuto” that is would be more helpful in memorizing things like maybe implementing something for practice. Also I kinda wish “Theory” had a thing in the scales section to learn about pentatonic scales and blues scales. Also to learn to apply concert pitch to different instruments. Thanks I hope you guys are improving things also honestly this app is extremely good you should honestly have people pay for it so you can have the time to update it and stuff and implement those things.

Truly Very Nice

I had needed a great music theory app, and this fulfills my need quite perfectly. The teaching is laid out in a very easy-to-understand format with attractive interactive user-friendly diagrams. By the end of the first lesson, I felt as if I’d learnt quite a lot. And all without any effort at all. It’s unbelievable! I already have an excellent practical practice app, in form of playgroundsessions app, that I had bought in a package deal along with a baby grand piano. But I had found the hands-on playgroundsessions teaching tool to be slightly lacking in deep music theory support. So I went looking for something to compliment the playgroundsessions hands-on app, and to hence fully round out my musical education. Now I have one app for hands-on practice, and this one, for in-depth theory learning. This is great!

Amazing! Just one thing to add

I didn't get into music theory until I got a guitar on a whim, then I wanted to try to actually learn music as a side thing, and now for the first time I feel like I actually know a little something about music. Only thing I would add to the app is something that you already have on your website (where I learned from, I downloaded the app and it's sister tenuto) is the pop-up piano that helped me figure out scales (I never learned piano so it was easier for me to visualize this way). Otherwise, thanks for you hard work!
