Signal is a free all-in-one messaging and voice-call solution that uses end-to-end encryption. Its developed by Open Whisper Systems and the App is available both on Android and Apple’s iOS. Their is also a desktop version for Linux, Windows and macOS.
Signal is greatly known for its fantastic messaging solution for security-conscious mobile users. Despite its renowned encryption in Zambia most users are stuck with WhatsApp, Facebook Messenger and other Apps because Chat App users tend to stay where most friends are.
With Signal you can send text messages, voice calls, group messages, media and attachments to your phone contacts, all without having to mess with PIN codes or special login credentials.
Another great feature is that messages can also be set to self-destruct after a certain amount of time. This makes Signal chat more bulletproof to the prying eyes and hackers.
