Very great, I loved it, something you could of done for more color is to change screen 2’s color to a different color instead of a lighter green (slight color difference/no REAL color change)
Your user interface should be intuitive for someone to use the first time without explanation. It wasn’t clear that I had to click/tap. Then when I did, only the text itself seemed to respond to the click/tap.
Having a “next” / arrow / “OK” button would be good.
