Can’t recommend enough

This is how educational/utility apps should be. Super easy to use, deep enough settings to get what you need, runs smoothly, and no ads

Well Done

This is a great app. Easy to use.

It would be even better if you could choose to change all of the Flat Major Chords to Sharps. Currently you can only choose making G flat into F sharp.

And if they could add a testing feature, it would facilitate one’s memorizing of the circle.
