And, surprise surprise, there are more dating apps in this world than just Tinder. We all know how Tinder works. The matches come to you based on your selected preferred radius, and the chat box will only open if you have a mutual match. And you only have a limited time to talk to someone before the chat gets closed. This means that you can easily declutter your messages and that your response rate will generally be higher. This site uses math to help users filter through their potential matches. It puts less restrictions on matches from different areas to message you, but to make up for it, OKCupid has a quiz feature.
