WeChat is an application that allows its users to keep in touch with each other. It works just like other apps such as WhatsApp, where you need an account based on your phone number. After you install the application, all your contacts that also have this app installed will appear inside the WeChat interface. The user can send text messages, pictures, videos, GPS location, and more.
When it comes to privacy, you will be happy to hear that the conversations are kept on your device and not on some remote server. You are the only one with access to your conversations done with other contacts or groups. Besides the text-based messaging system, WeChat also comes with support for voice and video calls. Each group video call can have a maximum of 9 people at the same time.
Inside the interface, there's a section called Time Capsule, where you can record and share short videos that will disappear in 24 hours. If you're holding some important conversations, and you need notifications when you receive a reply, the app can be configured to send special alerts when you receive a new message in your selected conversation. The sticker gallery comes with thousands of items, and you can easily browse through them.
