Tinder is a mobile dating app that allows users to browse photos of potential matches nearby and swipe right to "like" them or left to "pass". It has grown rapidly in popularity since launching in 2012, with over 10 million matches per day. While some see it as superficial or focused only on physical attraction, the CEO argues it mimics real-life interactions where appearance is initially noticed before getting to know someone. Studies also show users often match with others of similar attractiveness levels. The app has been adopted in many countries and led to over 1,000 marriages, showing it can facilitate more meaningful connections beyond just hookups. However, some remain uncomfortable with the judging of profiles or fleeting nature of online conversations.
