Extension summary

“All of my power is focused on my task; there are no distractions.”

Concentrating your mind and getting into a period of deep focus will make the effort and time that go into your tasks more effective. It will allow you to 'get in the zone', freeing your mind of distractions until your entire body, mind and soul become engrossed into the work.

Nucleus provides a simple, but effective UI to manage these periods of focus and relaxation. Nucleus is based on the Pomodoro technique for time management. When faced with any large task or series of tasks, break the work down into short, timed intervals (called 'Pomodoros') that are spaced out by short breaks. This allows you to immerse your mind, and get good work done.

Nucleus also includes the ability to block distracting websites so you can stay focused on your work.

The main problem is that sometimes it gets stuck in a loop and starts sending constant notifications, and you have to uninstall and install it again. Otherwise, it works perfectly.

This extension occasionally sends tracking information about me to an obscure server. This means they're harvesting my data. There's no reason why a simple extension to block urls and make timer should be harvesting user data. 0/5. Removed immediately
