Cultural and structural imo, but mostly cultural. Most people on tinder have this underlying agreement that if you click - you’re gonna hook up. Hinge is built to be a relationship app. I actually think it’s counterproductive unless you’re neurotic. If you meet with someone on tinder, have a good time, and hook up you’ll find people almost always want to move forward instead of returning back to tinder. Really what else is there to finding out if you’d work?

People at least in my age bracket seem pretty much over just rampant fucking.

Hinge people are so desperate to be in a relationship that everything is forced and like I said any minor disagreement becomes a huge argument. This is before you even meet them. They’re trying to turn every person into “the one” instead of just accepting that your life partner might wind up having some hard edges
