 -- Self Control --
A simple app to keep you focused online by blocking sites that you spend way too much time on.

Note that the app works by blocking patterns within the full url.
For example if you were to block the pattern "book"
the sites www.facebook.com and books.google.com would both be blocked.

Focus free mode prevents you from removing block patterns from the app for a fixed amount of time. By default this is one hour, but it can be changed in settings.

By default the extension is always running. To change this so that the extension only runs when focus mode is enabled, toggle 'Always on' in settings to Off.
