WeChat is a Chinese multi-purpose messaging, social media and mobile payment app. It allows users to send messages, make voice and video calls, pay utility bills, book rides, order food and more through mini-programs within the app. With over 1 billion monthly active users, it has become ubiquitous in China as a platform for communication, commerce and content. WeChat's success is due to its ability to be a 'super app' that meets all of users' daily digital needs in one place through constant innovation and expansion of its services.
