Doesn't include the full circle, but simple and useful.

It's a simple and useful tool, but it's missing C# and Gb at the bottom. But it's still nifty to explore in the early stages of learning the Circle of Fifths.

Doesn't work on Windows 10

Used to use it but in 10 it is a static frame

Simple to use

Very simple app. Tap the key in the circle to see the sharps or flats for that key signature. Could be nice with a few more options (I'm not a big fan of the color).

So, this app is just a picture?

It doesn't rotate? Well, not for me anyway. I figured it would contain more rings. That color just hurts.
