Usually, a blurry or missing profile picture is a major red flag on an online dating site. But on one dating app, it's the entire point: A new app called Twine blurs out its users faces on purpose so they can decide if they like someone based solely off of their personality -- not their looks.

The app connects you with up to four matches per day based on your proximity and shared interests, which are pulled from users' Facebook profiles. Because the faces are blurry -- and there aren't hundreds of options to check out -- users are more likely to zero in on individual conversations and, in theory, are more likely to find meaningful connections, says Twine founder Rohit Singal.

After you chat for a bit on the Twine app, you can opt to reveal your photo and first name -- and if the person you're chatting with also gives his or her permission, then your information and pics are exchanged. Users typically reveal themselves after exchanging about 50 or 60 messages, says Singal.

That may sound like a lot of time and energy to spend on someone whom you might not be into physically, but studies show that the more you know about a person, the more attractive you'll find them, says Singal. So once you find out you that the guy you've been chatting with swears by Starbucks pumpkin spice lattes, is obsessed with Breaking Bad, and never leaves home without his bike -- just like you -- you might be less likely to ditch him just because a Channing Tatum-lookalike just messaged you on OKCupid.

Of course, the Twine experience isn't what you're already doing in real life -- it should complement it, says Singal.
