Five stars, great app, I use it all the time in my songwriting. I was on the free version till today because I only buy apps with a one-time price -- I don't do recurring payments. So, thanks for adding that option. Only one minor issue: since buying the full version, the app randomly turns completely white with no usable screens. I force stopped it, cleared cache and data, reinstalled; it still does it. Just as randomly it starts working normally again, so I can live with it! ETA: Fixed itself

Useful app for reinforcement of music theory, quick references (with the means to try out the concepts) and expand your knowledge. You need to have some theory background, as it's not a teaching course in and of itself. Though you can learn more with it to enhance your knowledge of theory, as well as fill in some blanks. It covers a wide range of "tools" that may be a single app from other sources. It's like a complete toolbox. Kudos to the developer of this app.

I'm in awe. As I explore the app and tap on random buttons to see what it does, my husband started giving me funny looks because I kept saying, aloud, "Oh wow!" "Oh my gosh this is so cool." "It can do that too?" And the Matching Chords tool? 😍👌🏻 I'm a novice multi-instrumentalist with enough music theory knowledge to do the basic stuff. I've been trying to get back into it on guitar and piano, but this app is a goldmine if you're a musician. It's going to be so useful in so many ways.

For the purpose of a quick, practical reference that helps to bridge the gap between abstract concepts and the effort to make thoughtful, musical expression, this app exceeds my expectation. I began using this app with the thought that I could review the basics. Yet, I found that I was introduced to concepts I hadn't yet learned, and in a way that includes descriptive articles, clear diagrams, and triggered audio. It has proved itsel a useful composition tool.

There are other apps out there that do the same thing, but this allows you to learn how to do the same thing except this version is nice and easy. I'm practicing on the piano right now watching this. The developer really thought this out as a music teacher who could relate to tone deaf students and Perfect Pitch students and that's why it's my favorite

Info is always good and this app has it. Here is what is wrong with this app: 1.) The interface is very un intuitive, this app assumes you can figure it out right away, and has things placed, as though you have already gotten a walk through. 2.) The app does not communicate about it's mode of monitization, until you are already knees deep in frustrating menu's trying to figure out how to compose or even study with it. Overall pretty sus, if you ask me.

So far I couldn't ask for more out of a music theory app. This app helps me tremendously because I'm new to music. My only gripe is the subscription model for the vip hip. Shouldn't we be able to choose to subscribe or have a one time payment? I'm more than happy to pay say..$10. I believe this would be a win win. The consumer doesn't have to worry about yet another subscription service and I feel that the developers would make more money.

Android/LG phone. Used this for a long time but I'm deleting it. Ads were fine but now it has changed where the banner ads block the interface. Banner ad covers the drop down menus for scales and pushes the fretboard down where only half is visible. And asking a monthly fee of $5 just to view a couple of scales is a terrible idea. It was a *GREAT* app before these changes were made. Deleted.
