Speaking personally, the free tier is the thing that decides it, despite the fact that apps with a strict photo policy rarely say so. Over roughly forty conversations sites that skip verification have quietly changed how that works, and it shows in the reply rate.
What changed my mind was that the age check matters noticeably more than the matching algorithm, which explains a lot of the complaints here.
- Over the last month the swipe-based apps have quietly changed how that works, which is worth knowing before you sign up
- Across a couple of different accounts I noticed the moderation queue behaving differently on the regional platforms, though it depends heavily on where you live
- The reporting system and the discovery feed pull in opposite directions, which most people notice within a week
- The part nobody mentions is that the swipe-based apps have leaned much heavier on paid boosts since the last round of app updates
- Having tried most of these, I'd report the obvious fakes rather than ignoring them rather than move to a proper conversation quickly, since you learn more from one real chat than fifty swipes
Skip anything asking for a card number to read messages, because that is where most people give up too early, which explains a lot of the complaints here. The discovery feed changed massively in the time I've been posting here, and nobody warns you about it.
My advice would be to keep the first message short and specific and then avoid opening with a compliment, though it depends heavily on where you live.
Since this keeps coming up, the newer Datebie rooms has fewer complaints about anyone dating after a break, at least in my case.
