This App is the Cleanest, Most Concise and Easiest Interface for Guitar Chords that I have EVER seen! Some GUI suggestions (I am only reviewing the Guitar interface.)
1. Center the whole face! On my iPhone it is tagged to the Top with way too much Empty space at the Bottom.
Also make the Interface able to turn 180
2. Add the Sound of each chord!
3. Provide Color Schemes for Users
to choose from.

This could evolve into the Absolute BEST
Chording App on the App Store!!!!!!

Some severe problems

Context: I’m only interested in ukulele chords.

The first chord variation shown is quite often not a common, easy fingering. I wonder if the different inversions were chosen by algorithm, and not by a uke player. Take a look at D minor, for example - there are seven variations; the very last one is the common one. This will be bewildering for the beginning player. I don’t know if this problem affects the banjo or guitar chords.

In the iPad version, I can’t get any but the first chord variation to display. The series of dots in iOS apps typically indicates that swiping left or right will show different information; in this app, swiping does nothing. In the iPhone version, I found by frustrating trial and error that tapping on the left or right of the dots works. Even setting aside this bizarre user interface choice, at least it works on the iPhone. Not so on the iPad. I tapped away like a lunatic on every square centimeter of the screen, and I can’t get the app to show any but the first uke chord variation. This bug doesn’t affect banjo or guitar chords.

I do like the appearance, but the interface is weird and un-idiomatic; in the case of the iPad, it’s unusable. It doesn’t support split screen mode, which absolutely should be fixed, but not before those other problems.

Needs work

It's cool in a minimal way perhaps the simplest way to quickly access chords I've seen although they don't always seem to be the most practical voicings. The biggest problem I have with the app is that the options screen is completely non functional the only 2 things you can set are name length and show note options and neither works at all.
