Telegram: Secure Messaging App with End-to-End Encryption

Telegram is a cloud-based instant messaging app that allows users to send and receive messages, photos, videos, audio messages, and documents. It was developed by brothers Pavel and Nikolai Durov in 2013 and has since gained a large user base due to its security and privacy features. Telegram offers end-to-end encryption for messages, the ability to create channels and groups for sharing information with large audiences, and a self-destruct timer for messages that automatically delete after a set amount of time. The app is available on multiple platforms, including iOS, Android, Windows, and Mac.
