Chatting on Tinder is only available between two users that have swiped right on one another's photos.The selections a user makes are not known to other users, unless two individuals swipe right on each other's profiles.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.The average user would generally spend about an hour and a half on the app each day.After transitioning from the clicking function Tinder initially used, Tinder became the first "swipe app", now a term to describe various apps that use swiping left or right to control what content the user sees in a browsing fashion.As of November 11, 2015, Tinder's "Moments" feature had been retired.The Boost feature lets the user have the top profile in the area for thirty minutes.
Basic information is gathered and the users' social graph is analyzed.
Rad has also stated that Tinder filled a gap for social sites for meeting strangers, rather than connecting with people a user already knows.
By May 2013, Tinder was one of the top 25 social networking apps available on the web based on frequency of use and number of users.
Instead of swiping right for a profile, the user swipes up.
The app notifies the user if they have been Super Liked with a blue border that surrounds the profile of the person who Super Liked them.
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.
