Using Facebook, Tinder is able to build a user profile with photos that have already been uploaded.
Basic information is gathered and the users' social graph is analyzed.
If two users like each other it then results in a "match" and they are able to chat within the app.
In March 2015, Tinder announced the public release of its paid service, Tinder Plus, a feature allowing unlimited matches, whereas the free Tinder app limits the number of right swipes in a 12-hour period.
It then allows the user to either swipe right or left.
Tinder says that Super Likes makes it three times as likely for users to find a match.
In November 2016, Tinder introduced more options for users to select their gender.Companion apps were being developed by different companies allowing users to, for example, use the user's heart rate to determine which direction to swipe instead of the user swiping with their hands.The main companion site for Tinder has been Facebook, as Tinder users connect their Facebook profile to their Tinder accounts for verification and profile details.Information available to the users is based on pictures from Facebook, a short bio that users write themselves, along with linking Instagram and Spotify account.
Tinder is among the first "swiping apps", whose users employ a swiping motion to choose photos of other users, swiping right for potentially good matches and swiping left on a photo to move to the next one.However, to get to those 12 million matches, users collectively make around 1 billion swipes per day. As of June 2016, If a user of Tinder who is below the age of 18 attempts to use the app, they are met with cards on their deck stating that Tinder is no longer usable by anyone under 18, and that the Tinder team is developing a new app especially for their age group.
