Tinder, which was launched in 2012, is a social app that facilitates communication between mutually interested users. Users use a left or right swipe to choose photos of other users and potentially match with them. Tinder introduced a smart photos feature that increases users, ability to find a proper match, leveraging ML algorithms. This feature allows users to see the most famous photos first, as the underlying model is constantly learning and reordering the photographs by analyzing the swipe action behavior of the user.
