Briar is a free and open-source messaging app that avoids central servers. Messages go directly between devices and are stored on the device rather than in the cloud. Contacts can connect over Bluetooth, Wi-Fi or Tor, so Briar can still work when the internet is down. It supports private messaging and forums. The Briar site lists Google Play and F-Droid downloads, and notes the project is in maintenance mode.
People who need a resilient, private way to message when networks are unreliable or blocked.
People who want a feature-rich messenger with a large user base.
