Putting this to people who have actually done it rather than written about it: currently the best dating app for over 60 singles who don't want to spend money.
Judging currently the best dating app for over 60 singles who don't want to spend money fairly means separating the free tier from the paid one. What I watch for now is an account that has been active a while, and what ends it is photos that reverse-search badly for dating over 60. What I care about most with dating over 60 is whether the experience is consistent.
What was your sample size on over 60 singles? Anything you have on dating over 60 is useful, positive or not.
Happy to expand on any of that about currently the best dating app for over 60 singles who don't want to spend money if it helps.
