Tantan is a social chat application originating from China, first released in 2014, which mimics the popular dating app Tinder. Users select their preferred matches through simple "swipe left" and "swipe right" actions, and chatting can only begin if both parties like each other. This location-based matching mechanism has quickly gained popularity among young users, especially those born in the 1980s and 1990s.

In 2018, Tantan was acquired by the social platform Momo for approximately $771 million and became its subsidiary while still operating independently. Tantan has surpassed 360 million users and offers innovative features such as "passing by" and "anonymous confession" to enhance user experience and interaction. Despite facing controversies regarding safety and privacy, its continuous user growth and market expansion demonstrate its significant position in the social application field.
