SelfControl is a time management tool by Charlie Stigler and Steve Lambert. The application is designed for every user who wishes to focus on their tasks by setting a timer that blocks everything online. Users have to specify what websites and online services they need to avoid accessing and spending their precious time. They can also indicate how long should the application block them. This application will remain to block the websites even after users restart their mobile device or delete it. By blocking websites and other online services, users can read their study materials, do their jobs or pursue activities offline.
