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.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.Tinder says that Super Likes makes it three times as likely for users to find a match.As of November 11, 2015, Tinder's "Moments" feature had been retired.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.Chatting on Tinder is only available between two users that have swiped right on one another's photos.Basic information is gathered and the users' social graph is analyzed.Candidates who are most likely to be compatible based on geographical location, number of mutual friends, and common interests are then streamed into a list of matches.
Rad has also stated that Tinder filled a gap for social sites for meeting strangers, rather than connecting with people a user already knows.
The Boost feature lets the user have the top profile in the area for thirty minutes.
Users receive up to ten times the amount of profile views while boosting. If users do not have Tinder Plus or want more Boosts, they can be purchased in the app.
As of late 2014, an estimated 50 million people use the app every month with an average of 12 million matches per day.
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.
