Maybe like, at least the highest rated mobile friendly mods of the month or week could be somehow implemented as a free IAP (in app purchase) or something. I get this may be fairly impractical but, this idea may lead to some other kind of solution that does work.

facepalm
iOS mods aren't a thing, and will never be a thing. Just buy or use a different device.
