As others have pointed out, this app doesn’t due what it claims. I wanted to remove a small extraneous item from a photo and couldn’t find any way to do that. (It does allow you to crop and colorize, but why would I want a separate app to do that?) The user interface is puzzling and, on my iPad Air 4 running iPadOS 15.1, had the puzzling effect of requiring me to rotate my device because it displayed my photos upside down. Strange and not useful. I deleted the app.
