What does the WeChat heatmap do?

Like many other apps, companies want their apps to go global. This means that the app has already become very popular with the citizens in their own country, but they want it to spread to other parts of the world. To do this, the company like Tencent who makes WeChat, may wonder where their app is popular throughout the world. This is where their heatmap will help.

It will show the vicinity of their users when they are using WeChat. It may seem that the WeChat app is tracking their movements, but that is not the case. Instead, it allows the company to see where WeChat has become popular. It might show them where more and more people outside of China are using WeChat. This will let them know where to target advertising.
