I learned it with 5ths going counterclockwise, 4ths clockwise and the fact that you allow setting it one way or the other at the touch of a button is not only a huge addition but truly relaxing for my mind. Congratulations, astounding work. But why are you showing A# instead of Bb, D# instead of Eb, etc ? It is contrary to common sense. 😀😀😀😀 🎹🎹🎹🎹

Very useful little app. I just wish that it had the facility to display key signatures, which would make it 5 stars.
Grey Man
Super useful, but it would also be nice if there's a chord sequence finder to do reverse lookup with
Perry
its good and I paid for the VIP, but the problem is the settings always show a blank screen, so no settings and the ad screen on the bottom blocks the piano keys and never disappears, even after I pay for the VIP No Ads. These things need to be fixed. And I have an android phone.
