If I'm not mistaken, iOS apps aren't allowed to see what other apps are installed, is that correct?

It's nuanced, but you can use techniques like app URL scheme querying to determine what is installed. [1] People will be replying to you with information from 2011—today, it is generally not possible to query for a large number of installed apps this way. So generally, the answer is no.

Without going into much detail, the state of the art uses Facebook in a peculiar way to determine which _relevant_ apps are installed, relevant meaning high grossing (Clash of Clans, Spotify, Tinder are examples).

They're allowed to ask "does anything on this system handle yelp:// URLs?".
