Sponsor 96 - Objective 3: Update a diverse set of proven open source circumvention applications so they are compatible with new bridges and censorship resistance/detection techniques.

The Tor Project and its partners in this project have developed a set of applications that are proven to be useful for human rights defenders and their organizations, journalists, whistleblowers, and activists living under censorship and surveillance in China and other places around the world. The goal of this objective is to enhance these applications with our new bridges and censorship resistance/detection techniques. We will also execute a push to bring these apps to the mobile experience, as China, Hong Kong, and Tibet are mobile-first cultures

We have focused on mobile so heavily because most of our target users use mobile devices because they are less expensive and easier to acquire than desktops. Mobile devices are not only phones--this also includes all devices that run on Android, like tablets and televisions, and our project is designed to run across platforms whenever possible. We acknowledge that there can be challenges to focusing on mobile devices, because the censors are also focusing on phones. In some regions law enforcement requires certain apps be installed on every phone. When we build our tools, we are considering this threat environment and thinking about how to get around this kind of detection. All of this work will benefit desktop circumvention as well.
