Despite being a platform designed to be less centered on physical appearance, OkCupid co-founder Christian Rudder stated in 2009 that the male OkCupid users who were rated most physically attractive by female OkCupid users received 11 times as many messages as the lowest-rated male users did, the medium-rated male users received about four times as many messages, and the one-third of female users who were rated most physically attractive by the male users received about two-thirds of all messages sent by male users. Data released by Tinder has shown that of the 1.6 billion swipes it records per day, only 26 million result in matches (a match rate of approximately only 1.63%), despite users logging into the app on average 11 times per day, with male user sessions averaging 7.2 minutes and female user sessions averaging 8.5 minutes (or 79.2 minutes and 93.5 minutes per day respectively). Also, a Tinder user interviewed anonymously in an article published in the December 2018 issue of "The Atlantic" estimated that only one in 10 of their matches actually resulted in an exchange of messages with the other user they were matched with, with another anonymous Tinder user saying, "Getting right-swiped is a good ego boost even if I have no intention of meeting someone."
