Dating for discreet relationship
It's a cool concept and helpful for people who want to meet someone in a more organic manner.
Bumble also has a BFF feature, but that's really not the focus of a dating app gallery, so I'll save it for another time.
You'll need to wade through a sea of profiles, which makes it easy to pass over people you might have given a chance under different circumstances. I have friends who've met spouses through Ok Cupid. In fact, I've been on Ok Cupid, on and off, for roughly the last 11 years.
Profiles are much more in-depth than most dating sites, and if you answer a seemingly endless series of questions, they will spit out a reasonable Match/Enemy percentage ratio on profiles to help you gauge compatibility.
The downside is that short profiles make it harder to figure out what people are looking for.
Knowing very little about a person can also make initial messaging more challenging.
