Bass Guitar Colour Scales

Just paid and open this app. It has a button that will walk you through this app. Press it and you get the display panel. No instructions, App. Support simply takes you to the app page. I'm glad I didn't spend more than what I paid for because I lost this money on the app. Be nice if it worked, and yes, my Mac is all up to date.

Pictures make it look like it can be used in landscape configuration on iPad. Doesn’t seem to be the case. I’ve tried what I know but can’t get it out of portrait mode.

This is what I need to help get me through the pandemic! My knowledge and skill level will be far greater when I hit the stage again. Thanks for the more than thoughtful and educational content in this app. The intuitive layout and color coding is great! I no longer use bulky books to learn theory and scales.
