What is Signal and how does it work?

There is a great variety of messaging platforms available in the Google and Apple app stores, letting us communicate with our peers. The most popular and widespread of them all are Facebook Messenger and WhatsApp, but due to increased scrutiny with regards to how Facebook uses personal data in order to target you with personalized ads, people have started turning their attention to applications like Telegram and Signal that include extra security protocols. Furthermore, as conversations can bounce between the different messaging apps including Messenger, WhatsApp, Skype, iMessage, Instagram, etc., they are rendered confusing and unsearchable.

We have looked into what Telegram is in a previous post, so here we’re going to focus our attention to Signal.

What is Signal?

Signal, or also known as Signal Private Messenger, is a free communications app developed for Android and iOS devises. There’s also a desktop version available for Linux, Windows and mac. It employs end-to-end encryption, allowing users to safely send high-quality group messages including texts, images, videos, voice notes and files. You obviously need Internet access on your device in order to use it.

The end-to-end encryption means that messages sent through the app are always private, as long as both parties are using the app, and are engineered to keep your communication safe, meaning that no one can read or access your messages apart from yourself.

Signal allows you to keep chat history tidy according to your preferences, as you can choose which messages to disappear and when.

How does Signal work?

Signal look and works a lot like other similar messaging apps, which makes it easy to navigate your way through it. The app is especially convenient if you have family and friends about because it lets you sidestep expensive international SMS and calls fees. It also supports voice and video calls, so you can you it instead of Skype or FaceTime.

Simple does not support stickers or games, which is why it’s so simple and easy to use. It’s also easy to invite people to Signal. Once you’ve started using it, just tap the “invite” button inside the chat window and your friend will receive a notification from you with a link to download the app.
