For people who like a little extra hand-holding, CMB isn't the worst option.However, I found the app confusing to use, with too many features and too many gimmicks.
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.
I shouldn't have to look up online tutorials to figure out how to use a dating app. I was also disappointed in the notifications, which I found too pushy.
CMB was constantly "gently" reminding me to message users I'd matched with.
Changes in the last year have made Ok Cupid a bit more like Tinder, focusing more on swiping and eliminating the ability to message a user without matching with them first.
