-# Briar
-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 tools such as email, Twitter or Telegram, 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 information flowing in a crisis. If the Internet's up, Briar can sync via the Tor network, protecting users and their relationships from surveillance.
