4/5Very 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.

5/5Amazing! 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!

5/5Truly 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!

3/5Good but missing features
There is a practice mode that is on the website version. It seems like the app is a lackluster version of the website. For a more expensive alternative, I would expect either the practice exercises or other practice features to be implemented. A great offline version for the lessons but not much else. The website offers the same, comprehensive lessons as well as activities/ games to help solidify and check in on your learning for free. It has the most user friendly diagrams and lessons that I’ve seen compared to other apps.

5/5~ 9 years later
I have to say. I appreciate apps like this that stand the time with needing much updating. This app has been instrumental in learning music theory and what’s great is you can use it as a reference as well as a walkthrough. Love this app. Thanks to the developers
