Briar is an open-source, peer-to-peer messaging app developed by the Briar Project. Free to download and use, it provides its users with secure communications. It uses direct, encrypted connections, allowing you to exchange messages with any of your contacts without worrying about tracking.

Briar is described as a messaging tool for activists and journalists, although anyone can use it. Unlike traditional chatting apps, such as WhatsApp, it does not rely on a central server. Moreover, it works with or without an internet connection. However, your device's Bluetooth turns on by default. There are also some visibility issues present. 

What is Briar?

Briar is a messaging app designed for anyone looking for a safe, easy, and robust way to communicate. As mentioned, it does not rely on a central service, unlike traditional instant messaging apps. If the internet is up, it uses the Tor network to sync the users' devices. With this, it protects users and their relationships from surveillance. Moreover, all communication between devices is encrypted end-to-end.

Unlike other apps, it also works without the internet. When your internet is down, the app can sync via Bluetooth. With this, the information flow is maintained even during blackouts. The Bluetooth connection is based on the principle of a mesh network. Everyone extends the network by using it, which in turn extends help to others nearby to join the mesh and exchange encrypted messages.

However, there are some issues with the messaging app, the overarching of which is the lack of visibility into the system and messaging status. It is unclear how the app is connected to a network. With this, it is hard to troubleshoot when a problem occurs. It also does not indicate when the message has been delivered. Additionally, it does not display an icon when a message has arrived.

Should you use it?

Overall, Briar is a good alternative to instant messaging apps. It offers a secure connection between users, allowing you to send sensitive data without the fear of censorship and surveillance. However, how the app works is still a bit unclear. With this, you will have difficulty troubleshooting when problems occur. Not to mention, the app automatically turns your Bluetooth on, which drains your battery fast.
