I don't know why this has so many upvotes, it's pretty terrible:

- If the timer goes off while you are in the middle of writing a long post, mail or similar, all your work is instantly lost, no confirmation dialog
- unable to block specific URLs, it's the entire site and all subcontent or nothing. No way to block or allow anything finer than the main domain
- you have to chose between no timer overlay (and no timer in the extension icon either, so 100% blind), or a timer overlay that blocks site functionality under it, INCLUDING sites you haven't even limited

Does not work at all. Popped up once when I first installed it for one site and then never again. Have no idea how to use this or set what my limits are for what site. Terrible.

Got it to limit my time on youtube shorts. Didn't work for whatever reason.

Doesn't limit time while tabbed out of the window!

Worked fine for a couple of days, then suddenly the app disabled itself, and my list of sites became empty, and I couldn't add sites to the list (I click "add" and nothing happens). Disappointing.
