You discover potential matches based on searching instead of getting match suggestions, which gives you more control over your online dating experience. For each match you see, you also see the percentage match rate you have with that individual, giving you not just another conversation starter, but an actual data-driven indication (based on the profile questions you answered) of how well you and someone you find in your search results may match. OKCupid has a fun, laid-back feel to it, and users generally adopt a similar attitude when interacting on the site, making it a legitimate choice both for people looking for casual flings, and those in search of more serious, long-term relationships.
Hinge focuses on common connections that you and a potential partner share on Facebook. Which is great if you trust the judgment of your friends and family. Of course, some of us are trying to meet new people, far removed from our everyday lives. (Hinge may have come to understand that, since you no longer need Facebook to sign up.) The app also asks questions to help you match with better connections, which can be a plus for serious relationship seekers.
The site has profile verification options to ensure you are matching with real people and not fake profiles. On top of that, the site has a Smart Match system that essentially allows it to learn your preferences the more you use it, and the option to send a “Mega Flirt” that reaches dozens of inboxes every 15 minutes. It's a site you won't easily grow bored of that aims to help you become a better dater.
