It's made to keep you focused on the job, free from distractions. Usually the distraction looks the same: you have done some part of the job, it's time to have a break. You open YouTube, TikTok, Facebook and you are gone for hours. Deep Focus won't let that happen again. Simple 3-step process: 1. Add the distracting websites to a blacklist. Any website may be added. Simply type "website.com" and press "Add." Your blacklisted websites are stored in your browser.
  1. Click the "Enable" button to switch the application to active mode. From now on, whenever you try to access those sources, you'll see a banner reminding you to get back to work.
  2. Once the job is done, click on the "Disable" button to switch the extension back to passive mode. Now you're free to enjoy your favorite websites.
Key Features: - Customizable block lists - Real-time site blocking Technical Implementation: - Entirely client-side processing (no server communication). Your browser uses local storage to store the blacklisted websites. - Standard JavaScript (no minification/compilation) - Browser-level blocking. No mess with your operating system or router.
