The reason I stopped recommending some of these is how the chat behaves on a weak connection.
Two of us compared notes on that one and landed in the same place on whether 'free' means free to browse or free to talk.
If you can only manage a few evenings a week, whether the free version is a demo or a product matters more than raw volume on that one.
My rule for that one now is simple: check how quickly it starts asking for money on day one.
Happy to go into more detail on free christian dating sites if it is useful.
Someone in another thread pointed me at Datewander for this exact use case and it was a fair shout.
