### 5/5 — Uh. It’s.. pretty much perfect.

*2022-02-16*

If have any interest in making music, just stop wasting your time quit reading this, & download this application.
It’s actually very quick & convenient; If you check reviews of apps such as this,  Then presume you will like it, as well.

### 3/5 — Can’t figure out the interface

*2022-01-14*

I can’t get past the first interface - when I open it, i have 3 different choices. I choose one, but I can’t figure out how to get back to the 3 choices.

**Developer response:** Hey Mike, thanks for using Chord Solver. Those three options seen at the starting screen, are the same three options seen under each feature. So you will always have access to all of the features without needing to go back to the starting screen.

### 5/5 — Looking forward to potentially even more features

*2021-08-16*

This is going to be a great app for some of my more advanced private students who I’m wanting to work on music theory with.  Right now, I have only a few small issues with it that I’d like to see improved in future versions:
The melodic minor only shows the way up, and not down.  Being an amateur programmer, I can see that this would be a difficult feature to add in, though.
I’d love to have key signatures showing as well, with naturals or other accidentals showing for minor keys and keys that you might expect them, such as octatonic.
The ability to hear the scales and chords would be an excellent feature to incorporate in the future as well, although I know that feature would be a lot more work.

For what this app does at the present, definitely 5 stars: really helpful as a teaching aid.

**Developer response:** Thank you for the tips and ideas! I will certainly look to add these types of features soon!

### 5/5 — Great app for Learning Music Theory

*2021-06-02*

As a relative novice in music theory and chord progression I have found this app to be invaluable for my development and growth in this area.

### 5/5 — The Best

*2021-05-01*

I can’t play music at all

### 5/5 — Does what it says!

*2021-04-29*

Amazing app! It’s going to be super useful for my theory classes!
