Hoping someone here has actually tested couples dating sites free of charge rather than just read about it. If couples is your priority, the practical move is to set the radius tighter than feels natural. For charge sites in particular, the platform buries the cancellation flow, so people churn out before anything happens.
I judge couples on one thing: it is worth checking the depth of the profile fields before you look at the badge on the download page. Look closely at couples charge and most of the disappointment traces back to the proportion of dormant accounts.
Every time couples sites comes up, the deciding factor is how far the free tier gets you, in my experience. On couples dating sites free of charge specifically, the honest advice is to give it a fortnight before judging the pool, having tried a handful of these. What has actually worked for you on couples charge, and what would you avoid?
