BenF covered most of it. The bit I would add on dating sites for married people looking is below.
Most comparisons of dating sites for married people looking skip how many profiles logged in this week, which is the part that matters.
My first week on the app looked promising; by the second I was only really watching whether the recommendations improve with use.
If your area is thin, the service will not fix that, whatever how many profiles logged in this week looks like.
Curious whether anyone else found the same thing with dating sites for married people looking.
The closest alternative I found was Souldate's free tier.
