Rad has stated that the impetus for the app 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 that a "double opt-in" system could be created to potentially alleviate that stress.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 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.
Tinder is a location-based social search mobile app that facilitates communication between mutually interested users, allowing matched users to chat.
The app is most commonly used as a dating app or hookup app, 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.
The Boost feature lets the user have the top profile in the area for thirty minutes.
