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 4 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!UPDATE: Special Thanks go out to the developer(s) who have made Chordmate 4 even better now than ever before.Great job well done!!

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!

Would be cool if you could export PDFs and print. It says there is an option to export as PDF, but it doesn’t work. Just exports as their proprietary .cmprog file. Useless unless you plan on only using the app and not printing/exporting. Website doesn’t even have support, and their customer support email doesn’t answer. Edit: Customer support answered and provided me with workarounds but ultimately I went with a different app more suited for my needs. I could see this being useful for others

Developer was very quick to respond (<24 hours!), gave me advice and clarity on a few things I didn’t understand. FIXED a bug I found and submitted it to apple again in <24 hours! listened to a few suggestions I have and is looking to updating in future upgrades. And the price is totally respectable. what’s not to love.
