On Android phones. iPhone doesn’t have this privacy deficiency.

This was somewhat mitigated on iOS a few years ago.

You could try to communicate with an app via the custom URI scheme and if it succeeded, it would know you have the app installed. Twitter used this for finger printing.

An app has to get a special intent and has to list the apps it wants to use it for.
