What would you want?

If I made a child-free dating app and a separate child-free friendship app?

What kind of features and rules (like no fence-sitters, of course) (or no child-less people: people who want children and are sad because they can’t have them) ect.

For example, on the dating app, I would add a feature that is “sterilized people looking for other sterilized people”. Stuff like that!
