I met my wife at a running club. Of my friend group, most met while active in sports or other activities. A few were introduced by common friends on a "you might like so-and-so" basis. And a few met in college. I'm only aware of two couples in my extended friend group who met using dating apps - and both of those were premium subscription models, not freebie Tinder-like apps.
Dating apps strike me as a very low-quality (low fidelity?) way to match couples.
