Chordology is a multi-instrument chord dictionary allowing you to access to hundreds of thousands of chords.
- Includes chords for multiple instruments, including guitar, piano and ukulele.
- Shows sometimes thousands of variations of each chord.
- Minimalist, lightning fast interface.
- Supports both iPhone, iPad and OSX.
- Completely ad free.
Big update to how the chords handled. Currently, there are around 600,000 unique chords, each of which may have 20+ positions on each instrument.
This uses a huge amount of data, so i've had to re-think how they're generated and stored.
The method used for storing them has changed, which means faster loading times and far more chords (previously I had to leave out inverted chords as it increases the number of chords tenfold).
The lack of inversions meant that a lot of common Banjo and Ukulele tunings weren't possible!
- All possible inversions can now be selected for each chord (For example, a Cmaj chord with the G or an E as the lowest note).
- 4 String Tenor banjo added along with sounds. More banjo tunings to follow.
- Improved the quality of sound playback.

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!!!!!!

Thanks for this feedback, I know I am 3 years late but I finally got round to updating this one!
The app should now look a lot better on your device as it’s centred. I’ve added a light and dark colour scheme depending on how your phone is set (although adding custom colour schemes is a good idea too that I’ll look into).
I’m also planning on adding the note sounds too as soon as I get hold of some good recordings!
Let me know if you have any more feedback.
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.

Hi, I know I’m a bit late but thanks for this feedback! I’ve finally got round to updating the app and hopefully have addressed a lot of your issues.
Swiping problem: I agree that this wasn’t the best design choice, I’ve changed it now to be much clearer.
Chord sorting: You’re right in that the chords are generated using an algorithm (since I want it to be able to support any instrument in any tuning, it wouldn’t be practical to do it manually). I’ve tried to improve the sorting part in this version, so it tries to sort them by fretboard position and then by difficulty (it’s still not perfect though, I’m going to be updating this shortly soon as I sit down with each instrument and work out the best way and algorithm can sort them!)
iPad issues: I’ve fixed the major issues it had running on an iPad so now it’s useable, I’m planning on adding a iPad specific layout shortly too.
In the latest version I’ve also added two ukulele tunings depending on how you have the 4th string tuned (the app doesn’t currently show inversions, although I’m planning on adding this as an option as soon as I work out a practical way of doing it).
If you’re still interested in using it then drop me a message if you have any feedback or requests!
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.

Hi, I know I’m a bit late but thanks for this feedback! I’ve just release a new version with quite a few improvements and fixes. The chords are all generated by an algorithm, which is why the sorting can seem a bit strange sometimes, although I have spent some time refining it in this version!
With Family Sharing set up, up to six family members can use this app.
