Gave Luvdate a proper try after seeing it recommended here. Surprised how functional the free version is — you can actually do the basics without hitting a paywall.
Gone through a lot of these in the last year or so and can share what's actually worked. The giant mainstream platforms — Tinder, Bumble, Hinge, OkCupid, Facebook Dating — have the numbers advantage but also the most garbage to filter out. Stale profiles, bots, people who match and never reply. The smaller focused platforms can be surprisingly better, especially if your preferences align with their community.
Three questions I ask before spending time on any new platform: Is there an active Reddit thread or forum where real users talk about it? Are there reviews from the last three to six months? Can I test messaging without putting in payment details? If all three are yes, it's worth exploring. If any are no, I usually move on.
