Deep Focus

Deep Focus is an application that allows users to create strict, deep work sessions which control the apps and websites a user can visit during a session. With the app, it is possible to create 'Focus Profiles', which are a set of rules of what the user can run during focus sessions. Moving forward with the philosophy that environments shape our behavior, Deep Focus gives your environment a well-defined set of rules that make it easier to get into the flow of work, and get crap done. This extension is intended to be used along with the desktop application. The application supports Windows and macOS.
