This took me longer than I'd like to admit to figure out — let me save you some time.
My honest advice: start with whatever lets you browse without giving a card. That single filter cuts out most of the less trustworthy options.
Apps like Tinder, Bumble, Hinge, and Match are obvious suggestions but their restrictions make niche alternatives far more useful.
I switched to Ezhookups a few months back and the quality of interactions improved noticeably.
Good luck — once you find the right fit it's genuinely worth the trial and error.
