How to Make a Messenger App Like Signal

Today is the age of communication, so the chat application field is growing. To create a great messenger, you should understand how do chat apps work. There are two main types of protocol:

1. HTTP + Push Notifications. This means the way of work where you’re notified when you get a message, and the server responds back to you when you open an app.

2. XMPP with socket-based chat. This protocol works by constant user connection to the server. And the user automatically moves to the offline mode when the connection is lost. Extensive Messaging and Presence Protocol (XMPP) is more common-used.

The next step you should take is to make your app really secure. You should use end-to-end encryption. There is a way of work of this type of encryption: the user sends a message that gets encoded on the user’s device. Then it’s transferred to the server that brings it to the recipient. in the recipient’s device, this message gets encoded. This means that only conversation members can see decoded messages.
