Are you sure about the "Of course"? I just pulled up your app you sent me weeks ago, its right in front of me. Its not ASO optimized, at least not the title and subtitle which are the MOST important.
I just checked two languages:
German: You are using 17 out of 30 characters in for both title and subtitle.
USA: You are using 19 characters for title and subtitle.
This is not ASO optimized at all.
Your screenshots are also way too dark, its very difficult to differentiate the background from your actual UI. It needs improvement or replacement.
The app idea itself is alright, you can market this well on TikTok, but you would need to improve the UI for this. Make it more viral, more playful.
