I don’t think HN is the right place to post this and also I don’t think the title/slogin as fitting. This might be helpful to beginners, but nobody who’s scared of skill rot, will use this on a mobile app.

Honestly I think there is no benefit in any mobile coding app at all. It makes coding seem way more tedious than it is. I would rather recommend a book, laptop or youtube video than to do coding tasks on a phone keyboard.
