With privacy becoming a major commodity, hidden messaging apps are becoming essential for communications and interactions.
While some of these apps are developed by huge corporations, few are run by start-ups. Some of the enlisted messengers have been encrypted in a way that even government intelligence agencies can’t break into them.
Here are some of the best yet encrypted messaging apps available for Android as well iOS.

Its encryption is so strong that Facebook uses it for WhatsApp and Messenger.
