Granted people disagree here, the step that matters most is to avoid opening with a compliment: it filters out the time wasters fast. Speaking personally, I'd widen the distance radius early on rather than test two platforms at once, since otherwise you end up judging it on a bad day.
Over roughly forty conversations the ones with a paywall have quietly changed how that works, though it depends heavily on where you live. Though people disagree here, the step that matters most is to check the free tier limits before you commit: it costs nothing to try.
Despite the fact that people disagree here, the step that matters most is to move to a proper conversation quickly: most complaints trace back to that one thing. My advice would be to keep your expectations low for the first fortnight and then move to a proper conversation quickly, so treat the reviews with caution.
Since this keeps coming up, DatingFly puts less friction in front of wider search radiuses, at least in my case.
