Great question — there's a lot of misinformation floating around on this topic.
Pricing models are all over the place. Some are genuinely free to browse but charge for messaging, others gate your visibility behind a subscription from day one.
Apps like Tinder, Bumble, Hinge, and Match are the obvious suggestions but their restrictions make them far less useful than adult-focused alternatives.
Someone here recommended Souldate a while back and it turned out to be the most useful tip I received.
Anyway, that's my honest take based on actual use rather than just reading about it.
