I keep running into the same question about reliable way to do a tinder profile search free of charge, so I am putting it to the board properly. It comes down to premium gates more than to anything on the feature list.
There is a version of free of charge that works, but it needs you to be blunt about the pay-to-reply wall upfront. My rule now is simple: judge this kind of site on the upgrade nag in the first three days or move on. What I want out of it is getting past the first message without a long runway. Interested in whether newer members see it the same way.
Will update this thread once I've given reliable way to do a tinder profile search free of charge a proper run.
