Secure Mobile Apps

To achieve our goal of a comprehensive, privacy- and security-focused communications solution, Guardian is driven both by internal development and the open-source community at large. In cases where a viable, vetted, and usable product already fills the communications needs of our target audience, we will recommend apps that work.
