Tinder is a location-based app that uses social graph (interests, etc.) data and the number of mutual friends from Facebook to match you with potential partners. Users can choose to ‘like’ or ‘pass’ matches and if two people ‘like’ each other, it will open up a chat where they can talk to each other.
Tinder isn’t specifically a dating app but that seems to have become one of its primary uses. While some people have actually found love using it, most other people use it just for fun. Here are some of those ‘fun’ conversations, some of them are a bit NSFW (text).
