With this mode enabled, Focus blocks the entire Internet.
To add allowed websites, add them similar to how you would normally add blocked websites with Focus.
Focus can only be used in Block Mode or Allow Mode, not both. However, you can still add website exceptions to combine the two modes and handle any case you need.
Now that you've learned about the major Focus blocking modes: Block List and Allow List, learn how Scripting allows you to integrate Focus with other productivity apps, creating complex workflows that enable you to work exactly how you want.
