I keep going round in circles on which free dating sites for mature singles have and I'd rather ask than guess. Look closely at mature sites and the honest advice is to read the newest reviews rather than the top-rated ones, from what I've seen. With events, what decides it is how much sits behind the paywall, not the price tag.
It is worth separating out an older membership here, because with events, the platform resets your filters after an update, and the proportion of dormant accounts suffers for it. I judge events sites on one thing: it is worth checking how honest the pricing page is before you look at the length of the feature list.
Same story on events: how many first messages actually land is the number worth watching, not the app store rating. The churn on new sign-ups collapses as soon as the platform caps how many searches you run a day — and that goes double for which free dating sites for mature singles have. If you have been through the events sites version of this, I would rather hear the unglamorous account.
