What is different from WhatsApp
The Signal app allows users to send messages, make audio and video calls, share photos, videos and links. The app claims that user data is rarely used on its behalf. It also does not send unsecured backups of users to the cloud and it keeps the encrypted database secure in your phone. Also, the security of the app has been given an option to decide on its own. Signal has also brought the option of group video calling in December 2020.
