These dating apps are the equivalent to a pair of khakis from The Gap; there's absolutely nothing wrong with them, they're just overwhelmingly bland compared to what else is out there.
Ok Cupid, Match and Zoosk are standard fare for traditional dating websites.
That's not exactly the most optimal dating environment.
All require you to log into your Facebook account, however none share your dating details on the social network.
If you're uncomfortable being primarily judged by your photos, you're better off with a more traditional site like the ones listed above, where you can impress your future suitor with more details in a meatier written profile.
Religion and faith are driving forces for many people, resulting in the desire to date someone who shares those beliefs, too.
So, you're an "important" person who can't have their dating profile on just any dating site -- or you want to date an equally "important" person. The League is for anyone who admits they have high standards AKA very picky.
It requires you to sign in with Facebook and Linked In (to avoid setting you up with friends or co-workers) and you can set super-specific criteria.
