What decided it for me with free dating apps for men was whether the ratio is workable in your area.
Gave that one a fair run over 3 weeks and kept coming back to how much control you get over who sees you.
Given how whether the algorithm is doing anything useful behaves, I would only recommend the app to someone with patience.
The measure I would actually check on the platform is how much of it's usable without a card.
Whatever you land on, test free dating apps for men for a week before you judge it.
Different crowd on Datescout if you want a smaller pool, which suited me better.
