ChordMate 4 4+

As a jazz guitar instructor for 50+ years, I have been using ChordMate since its first release many years ago. I have found it to be the best and finest chord progression charting application available for both IOS and Mac. It is pre-loaded with hundreds of chord graphs, and allows the user to custom create their own graphs, which is indespensable when charting many difficult jazz chord progressions for guitar students. It also allows you to play chords as you enter them to be sure you have selected the right chord voicing.
If you are searching for the best chord progression charting app, ChordMate could well be the last application you will ever need. A special thank you goes to the developers of this application for writing such a superbly written and intuitive chord charting application!

I have been using this app for years to help annotate songs for my students. It is quick and easy to create a custom diagram, or to do a chord search, or a reverse chord search.

There is no other guitar chord app that even comes close to this. I would say this is a “must-have” app if you are a guitarist! Thank you for continuing to make such a truly unique and necessary app available to the world!
