Долго искал подобное решение и наконец нашёл идеальный вариант

Для учебы самое то

Excellent. My only complaint is that I can't write down the time; I feel it would be easier that way. The colours aren't my favourite, but that's a minor detail that doesn't affect it.

Could you add the ability to save my working hours and breaks? Right now, after restarting the browser, I have to set my preferred values again.
But overall, this extension is the best I’ve seen!! Simple and functional at the same time! Thank you so much for this solution. I’ll repeat myself — I’m really glad it’s not overloaded with unnecessary features.

Great app! Found it on reddit.

Loving the simplicity. It's minimalistic, yet has all of the necessary core features 5/5

I've been using it for one day but it is very easy to change the parameters.

خیلی خوبه، اگه مدت زمان سپری شده رو به صورت عدد در تولبار نمایش بده عالی میشه.

Very clean and nice.
Suggestion: let the user choose the colors. (At least to swap the default colors between the modes).

works good for me
