Signal Private Messenger (also referred to as Signal app) is a cross platform messaging application for Operating systems such as Android, iOS, Windows, Linux Variants etc. The app was found in the year 2018, by a Non-profit organisation, with a heavy emphasis on security. Another plus point for the app was that its founder Brian Acton, was the co-founder of Whatsapp. The app aspires to provide a Strong Security Framework which is transparent to the users. No private user data is collected throughout the working of the application. The application ditches some of the standard messaging application features, but makes up for it by providing secure data communication.


Telegram Messenger (also referred to as Telegram) is a cross platform instant messaging application for Operating systems such as Android, MacOS, Windows, iOS etc. Founded in the year 2013, the app has become one of the most popular messaging apps in the Mobile Apps Marketplace.
