Very anecdotal, but in my experience people have no attachment to or enthusiasm for dating apps. I've heard (acquainted) couples say the met on dating apps. No one ever said which ones.
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.
