My counter anecdote would be that almost every time I mention my spouse and I met on a dating app, people ask me which one.
Edit: people ask me which app, not which spouse.

I don't know if anyone who's asked me has started using the app as a result, but I think it (anecdotally, again) supports an idea that a successful results for one app organically helps its name recognition.
Edit: unless you meant the difference was between people asking which app vs which spouse.
