I was looking for an app similar to Screen Zen which I used on android and this works just as well. Helped me go from 2-4 hours of YouTube every day to about 50 minutes a day, the fact that it shows you your time for the day makes you more aware of the amount of time you waste on useless videos, which helped me start to bring down my time from 50 minutes to about 20 minutes in the past few weeks. This extension really helped me make another big step in my life.

does what it says it does, would be better if it didn't let you see the page it's blocking imo

This extension has helped me a lot with reducing time in social media. The use of timer adds enough friction without leaving me feeling restricted. And the fact that it's free is the cherry on top.

Perfect, and highly effective!

Great for distractions

This should be a must on environments that you intend to use productively. It let be put a check on the habit of opening new tabs and immediately opening youtube when I should be doing something specific. Don't love the request for 5 stars. I'd given it anyways but the side window (even if I can close it) is kind of annoying.

Thoughtful and privacy-respecting dev. Extension is very useful with the potential to change your life for the better.
