What is the Facebook dating app and how does it work?

The Facebook Dating app is a feature integrated within Facebook's main application that provides users with a platform to find love and start relationships. By creating a separate dating profile, which is distinct from their main Facebook profile, users can engage with others seeking romantic connections. The app suggests potential matches based on preferences, shared interests, and mutual friends while ensuring safety and privacy as user profiles and dating activity are not visible to friends on the main network. The robust set of features includes Secret Crush, where one can express interest in up to nine friends who will only know if the feeling is mutual, and Events and Groups that let users connect with people who have similar interests. Facebook Dating also offers the ability to share details of upcoming dates with friends to ensure safety during meetups.
