Needs lessons on sus chords.
I love the app and I find it very useful, but it lacks any information regarding suspended chords.

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

IPad issue
None of the directional arrows work, nor any other guidance symbols. Also, text panels are cut off at the bottom and cannot be resized. The course does not begin at the beginning, and I can’t go back to see what I missed, though having some theory already, it’s mostly review at this point. But if you’re going to charge ANYTHING, make sure what you’re charging for actually works.

Review of musictheory.net
Musictheory.net is an excellent free resource for teachers and students. Being technologically challenged, I like the simplicity of it. The site accomplishes its purpose without frills. Though it might not be as exciting as an online game, it seems to challenge students appropriately. It can be used to teach a new concept or review old concepts, as an assessment tool, and for students to practice. Student can easily go online and practice, put their knowledge to the test, or complete an assignment. I am eager to use the Interval Identification exercise for students to practice and track their own progress.

Good 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.

A lot left to be desired
This app would work as referenced to those who are thoroughly trained in music theory NOTFOR LEARNING IT

Awesome app
Would highly recommend

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!
