One matchmaking app that is very focused on physical appearance is Tinder. Tinder connects people through the use of their social network of friends and acquaintances on Facebook. Based on an algorithm, Tinder shows the user potential matches and then allows the user to anonymously like or reject these potential matches by swiping or tapping. If two users "like" each other, it results in a "match," and Tinder allows them to chat. However, the app has been heavily criticized for being "shallow" and focusing too much on external appearances. Do you agree? What do you think about? how will affect the marketing in the future?
