There are people who are easily distracted from their task whenever they hear or see something. As a result, it takes them longer hours to complete their work. Instead of going back to their priorities, they will just check their phones until they do not even notice it has already taken so much of their time.

With this extension, Fokus helps a user to continue doing their tasks by blocking certain sites that may get in the way of their productivity. You can track how long you have been studying or working already.

This is a free tool and can also work offline.
