All the data are transferred with TOR(The Onion Router), which is highly untraceable.

With more functions such as Group Chat, Forum, and Blog, all the data is locally stored, meaning there is no possibility for your data to be censored or deleted.

The Cons:

1、 目前仅有安卓版本

Briar only supported by Android, not for IOS for now.

2、 由于没有中心服务器,所以APP必须常驻后台,影响手机续航。一旦后台进程被关闭,就收不到信息了

It has to keep background refresh or fail to receive any message due to the absence of centralised servers.


The account is NON-Transferrable. You have to run the account on only one single mobile phone, otherwise you will reconfigure your account on your new device.


Briar is a messaging app designed for activists, journalists, and anyone else who needs a safe, easy and robust way to communicate, intending to provide secure and resilient peer-to-peer connection with no centralised servers and minimal reliance on external infrastructure. In simplicity, to turn your mobile phone into a digital radio station.



Briar runs seamlessly on Android mobile phones, and displays perfect performance. The app requires background refresh to receive the message as there is no centralised server. To the surprise, Briar runs stable, without facing any unexpected shutdown. The communication function in the absence of internet infrastructure works well, and the message sending and receiving is fairly efficient.

In the movement against the extradition law in HongKong, Telegram played the greatest part in communication. It illustrates an excellence of experience as well as group chat and broadcast Chanel, allowing hundreds of thousand netizens to stay online simultaneously. Telegram makes the marching organised and exonerated of chaos. The problem is, however, telegram relies on 4G service which is less stable when a unexpectedly large group of people flock into the area, which can cause crackdowns of the service.


To deal with this situation with no internet, the activists turned to use Firechat in OCLP(Occupy Central with Love and Peace) in HongKong, 2014. Unfortunately, Firechat shows terribly unstable performance and unsatisfying user interface. Besides, the relay pattern employed by Firechat may lead to data leaks and man-in-the-middle attack. These are the reasons why Firechat was not used massively. Briar came out without these issues, which means highly suggested for mass movement, such as HongKong(free of the Firewall).


To the worse, the government takes away the internet when it occur to Mainland China's citizens to participate the protest, Yangluo, Wuhan for example. Briar should take a great part in the activities after the internet being shut down. A mesh net work consisted of a unlimited numbers of industrial mesh routers and battery packs can be set up to extend the range of the Wi-Fi direct or Bluetooth.A mesh network can easily cover an area in the radius of hundreds of meters. What it takes is to set up the Wi-Fi without a password, and there is no need for Internet to be involved.

使用MESH路由器组网,可以让WiFi信号无限扩展  With Mesh Routers involved, the Wi-Fi Connection can be extended to an unlimited range.

It's getting worried that the CPC(Communist Party of China) will totally block the international internet. From my point of view, it's nonsense, as the Internet is decentralised. They may cut off the Submarine Optical Fibre Cable, but not to the satellite. They are all solvable technically. Unfortunately, the public had lots of habits, which are something that cannot be solved. It's not a secret that Weibo and WeChat are under surveillance. Nonetheless, there are sill tons of people talking about sensitive topics, and then suffering punishments from the fingermen in China. Frankly, they deserve it. They don't even protect themselves.


Briar is an app of excellence designed for the communication between acquaintances. Less known and more Secure. It worths every activists responsible to their safety to download and use.
