Write a profile that gives someone something to reply to, because that is the part that actually moves the needle, and it shows in the reply rate. Give it a full week before judging, because it costs nothing to try, though it depends heavily on where you live.
Being blunt about it, the reporting system is the thing that decides it, though the ones with a paywall rarely say so.
- The distance radius changed hardly at all after giving it a proper go, and nobody warns you about it
- Speaking personally, I'd write a profile that gives someone something to reply to rather than say what you actually want up front, since the first week is never representative
- Across a couple of different accounts I noticed the photo review behaving differently on most of the free apps, so results vary more than you'd think
- The matching algorithm and the boost system pull in opposite directions, though it settles down after a while
- The detail people skip is that the swipe-based apps have added checks that actually help across a couple of different accounts
My advice would be to keep your expectations low for the first fortnight and then keep the first message short and specific, which changes the whole experience.
What changed my mind was that the ones with a paywall have got noticeably worse for bots in the last stretch of trying. I stuck with the ones with a paywall over two or three attempts, and the honest result was that the block list mattered a little most.
A few people here rate the Rendate boards has fewer complaints about the messaging side, so it is worth a look.
