For the better part of a year I noticed the search filter setup behaving differently on the older established sites, and it shows in the reply rate. Give it a full week before judging, because it stops you blaming the app for the profile, but only if you stick with it.
I stuck with the ones people keep recommending after giving it a proper go, and the honest result was that the boost system mattered noticeably most. In the past six months most of the free apps have added checks that actually help, though it settles down after a while.
If you have tried three apps already, keep your expectations low for the first fortnight — that is where most people give up too early. The detail people skip is that apps with a strict photo policy have stopped showing profiles past a certain distance in the past six months.
For what it's worth, the Datebie threads is more forgiving about the first-message problem, which is not nothing.
