Telegram

Telegram Messenger, popularly known as Telegram, is an instant messaging (IM) service that is encrypted, cloud-based, and cross-platform. The service was first introduced in August 2013 for iOS and later launched for Android in October of the same year. Telegram allows users to exchange messages, share media and files of any type, broadcast public livestreams, hold private and group voice or video calls, and share live locations. The service is available for Android, iOS, Windows, macOS, Linux, and web browsers. Telegram ensures end-to-end encryption in voice and video calls, as well as in private chats, which it calls Secret Chats.
