Block Site Ex is a website blocker for the Chrome platform. It allows users to set up a PIN code and a flexible schedule for blocking websites. With a four-digit numeric PIN code, users can easily block specific websites. The flexible schedule feature allows users to set specific times when the blocking is active, giving them control over their browsing habits.

One of the key features of Block Site Ex is the ability to protect the settings with a PIN code. This ensures that only authorized users can access and modify the blocking settings. The program is designed for personal use and provides an easy way to block distracting or harmful websites.

To use Block Site Ex, simply enable the blocking feature on a website via the toolbar icon. You can find the "Block Site Ex" toolbar icon under the puzzle icon in the browser toolbar.

Please note that while Block Site Ex provides an effective way to block websites, it is important to remember that any tech-savvy person can easily bypass the tool. Therefore, it is recommended to use it as a personal aid for self-discipline rather than relying on it for strict security measures.
