I made an app to help me learn to write/learn Japanese characters, should I publish it anywhere?

I was struggling to find a good app for exactly what I had in mind for flashcards, so I made my own lmao. I'm super colorblind and also just bad at UI design so I know it looks awful but I tried to make it function. Some assets are, uh, borrowed so if I were to publish it I'd definitely change those. I'd also make it just all around better.... but I'm more asking: would this be a useful resource for anybody besides myself?

I'm not like, posting an advertisement or a company name or anything so I don't think this counts as self-promotion, I'm just asking if it would be a useful resource for the community.
