Briar is a messaging app designed for activists journalists and
anyone else who needs a safe easy and robust way to communicate.
Unlike traditional messaging apps Briar doesn't rely on a central
server - messages are synchronized directly between the users'
devices. If the internet's down Briar can sync via Bluetooth or
Wi-Fi keeping the information flowing in a crisis. If the
internet's up Briar can sync via the Tor network protecting users
and their relationships from surveillance.
