You know what's hard to find on a dating app?

A man who writes decent English.

A man who can have an intelligent conversation (I definitely want to see if he has brains before I commit to meeting).

A man who is transparent. The minute they start avoiding certain questions like "What do you do for a living? Where do you stay? Where do you work?" Anything that will enable you to identify him makes him slip away.

Basically, it works both ways.
