Have you ever been distracted by your desktop? Notifications, post-its, reminders, folders with weird names, background pictures? All this stuff can easily distract you and prevent getting focused.
If you are a writer and you need to be concentrated on the current draft, Focused is very helpful. We you run Focused you are in front of a full screen application, which shows you just a text box. This prevents you from having a look to other windows or tools that are potential distractors.
The only thing you’ll see is just your text. Try it!
