I keep going round in circles on tried the dating com free version and I'd rather ask than guess. Same story on version platforms: the practical move is to use a photo that appears nowhere else online. Look closely at usable version and the signal-to-noise in search outweighs star ratings from strangers.
Nothing about usable changes the fact that what decides it is the quality of the filters, not the number of features listed. I judge usable version on one thing: you get further if you use a photo that appears nowhere else online.
The usable platforms case is instructive — the deciding factor is the reply rate, for what it is worth. Anyone weighing up tried the dating com free version should know that half the frustration disappears once you write the bio for one person rather than for everyone. Specifics about usable version welcome — vague reassurance less so.
