Tinder is a location-based social search mobile app and Web application most often used as a dating service, that allows users to use a swiping motion to like (swipe right) or dislike (swipe left) other users, and allows users to chat if both parties like each other (a “match”).
Tinder originally required access to a Facebook account of the user of Tinder but, as of 2019‑08‑17, Tinder allows users to register using a telephone number and without access to a Facebook account.
Tinder's primary companion site has been Facebook, as Tinder users were originally required to connect their Facebook profiles to their Tinder accounts for verification and profile details.
Using Facebook, Tinder is able to build a user profile with photos that have already been uploaded.
