What’s New

Version 2.3.0

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.

Any comments, criticisms or bugs found then please drop me an email at []( and i'll get back to you as soon as possible!

Ratings and Reviews

Love the design!

Been using this for a while as it has way more variants than most websites and is much faster. Some of them are quite hard to play so it’s maybe not the best for beginners, but they’re all there!

My only criticism is that it doesn’t let you change the tuning besides the preset ones (and being able to add a capo position as well would be really useful).

Developer Response ,

Thanks for the review! I’m planning on adding some more tunings and instruments, email me if there’s any you’d like in particular.

After purchasing the Chordology app for only 69p the first thing i found out was that every chord you need to know is available at the price paid so there is no paying again. Chordology makes everything visible and easy to understand.
We review many apps daily and we are always looking for the next best thing, by far Chordology is a great app for a great price and I would recommend beginners and advanced people alike to use it.

Well done to the designer and thank you, kind regards AppStorereviews™.

Just what I needed, better interface than the other ones and doesn't crash every 2 seconds like the other one I bought.
