Tinder keeps track of every user’s “attraction score”

Dating app Tinder keeps a score of how desirable users are without users noticing, in order to better match them with other users. Tinder employees can look it up using an email address.

If a user who has a high rating himself rates you as attractive, it earns more points than if someone with a low rating does, according to a Fast Company article on the subject. The score would therefore be comparable to the Elo rating in chess.

The ranking would be necessary to better match users, say Tinder employees in the story. Users will not get a chance to look up their Tinder rating. It will remain an internal Tinder tool that works in the background. Employees only need an email address to find out that score in an internal system. It is unknown what the scale of the rating is.

It is the first time that information about the ranking system of Tinder has come out. The Tinder app allows a user to rate another person based on a photo, after which the program can make a match based on that rating. After a match, contact can be made via a chat window.
