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.
The information available to users is based on pictures, a short biography, and, optionally, a linked Instagram, Facebook or Spotify account. Tinder originally required access to a Facebook account of the user of Tinder but, as of August 2019, Tinder allows users to register using a telephone number and without access to a Facebook account.
Tinder was launched in 2012 within startup incubator Hatch Labs, a joint venture of IAC and mobile development firm Xtreme Labs. By 2014, Tinder was registering about one billion "swipes" per day.
Only a few years ago online dating was that thing many of us assumed that only desperate or creepy people did, and no-one dared admit to searching for or having met their partner online. There are plenty of great dating apps out there, but there's one app in particular people are using: Tinder.
