Tinder is an American geosocial networking and online dating application that allows users to anonymously swipe to like or dislike other users posted profiles, which generally comprise their photo, a short bio, and a list of their personal interests. Once two users have matched, they can exchange messages.

Why is the app called Tinder?

Tinder is an app that makes matches. Starts the spark, so to say. This is an excerpt from Rewind and Capture, which explains why they chose the name: The idea of setting a spark, of starting a fire, for romantic relationships was always the log-cabin foundation for Tinder, which was originally called Matchbox.
