Signal is a free messenger client, like Facebook Messenger or WhatsApp. Just like WhatsApp and Telegram your account is tied to your mobile number. Users who are used to WhatsApp should find Signal familiar enough to use without any hand-holding.
Signal’s priority is user privacy. It is developed by the registered non-profit Signal Technology Foundation. End-to-end encryption means that your data is protected, even from the makers of Signal. Read about what happened when Signal received a subpoena from the US government
Signal has most, if not all, of the features you would expect from a messenger app, including …
- End-to-end encryption
- Photo and file sharing
- Voice and video calling
- Groups and group calling
This is a very short list, check out Signal’s support site to learn about all the features offered.
