Older version was better

November 14 update: the developer has kept his word and updated the app to address my gripe. Thanks!


The older version was better. In the older version, when you pressed on the keys in keyboard piano, it would produce the note. When you press the second time it wouldn't as if to turn the note off. The new version makes it sound both times. This is very distracting. Hopefully the new developer will fix this. Otherwise, the app is perfect.

Easy and very detailed!

This app is really great! Its detailed and will give you all the possible chord names for anything you play. Plus you can view the note names, fret numbers, or chord note intervals and switch between those options seamlessly for teaching yourself and expressing chords to others! I really like this app!! Works great on guitar or piano.

Very pleased

This app is what I was looking for. The only thing I would like see is an option to see the guitar , piano and music notation of the chord on the same screen. If not then a toggle button so you don’t have to go into settings to change the display. Would be nice for an export into pdf also.
