WhatsApp Tests Interoperability with Other Messaging Apps, Including Arattai

Imagine you have a special phone that can only talk to other phones of the same kind.

WhatsApp, a very popular app, is trying to let its users talk to people who use different apps, like a new Indian app called Arattai.

This is like a test happening in Europe for now.

The reason for this test is a new rule in Europe that wants big apps to work together, so no single app becomes too powerful.

Arattai's creator believes all messaging apps should connect easily, like how different payment apps let you send money.

For this to happen, Arattai needs to use a special secret code for messages, which they plan to add soon.

It's not yet known if this feature will come to India or other places.
