WeChat is an app that has become very popular over time. It was first used and created in China. You can download WeChat off of the Internet for free. Then you can set up your account. You can post pictures on WeChat as well as communicate with others using this app. You can even call and speak to people internationally for free. A superapp is an app that has more technology than the other similar apps out there.
This means that it is more powerful and can allow for international communication through their language problems and cultural differences. WeChat is considered to be one of these superapps based on the many things that it can do internationally. Other apps cannot do the same.
