Honest question: What are the worst dating apps you've ever installed?
Speaking generally, this might seem straightforward but the answer varies a lot depending on who you ask and what their incentives are, though I would not bet the house on it. Realistically, every 'expert guide' I find seems to be monetized in some way that makes their recommendations suspect, at least in my experience. For what it's worth, I'd rather get unfiltered takes from people in this community who don't have a financial stake in pointing me anywhere specific, which is not a universal experience.
Personally, even a short 'yes, still works' or 'gave up on it because X' is genuinely useful, at least that has been the pattern. I'll take a thread full of mixed experiences over a polished review any day, which matters a lot for worst dating apps you've.
