Sign up, create your profile, and answer a barrage of questions on everything from politics to sex positions. The app then uses a logarithm to find you the most compatible matches around. Similar to Tinder, OkCupid utilizes a location-based service and proposes potential paramours within a certain radius. Sure, there's a swipe-left and swipe-right arm of the app, but there's also just a standard browse and message format that's simple and effective. It's all about the power of your profile though, so spend a little extra time and don't choose The Shawshank Redemption as your favorite movie. You liked it, but so did everyone else.
