If two users like each other it then results in a "match" and they are able to chat within the app.
The selections a user makes are not known to other users, unless two individuals swipe right on each other's profiles.
As of late 2014, an estimated 50 million people used the app every month with an average of 12 million matches per day.
Companion apps have been developed to provide different actions or mechanisms to accomplish Tinder's swipe function.
By May 2013, Tinder was one of the top 25 social networking apps online, based on frequency of use and number of users.
Initially, instead of utilizing Tinder's current swiping motion for making matches, users had to click either a green heart or a red X to select or move on from a displayed photo.
Rad has said the impetus for Tinder's creation was his observation that "no matter who you are, you feel more comfortable approaching somebody if you know they want you to approach them." He believed a "double opt-in" system could be created to potentially alleviate the stress of meeting new people.
Rad has also said Tinder filled a gap in the availability of social platforms for meeting strangers, rather than connecting with people a user already knows.
However, once you have matches on the app, the user is able to send personal photos, called "Tinder Moments", to all matches at once, allowing each match to like or not like the photos.
