Stop overworking. Get away from keyboard.
I often stay glued to my monitor for hours without realizing how quickly time passes.
Sometimes, I need to stand up and take a proper break. This app helps enforce that. After a set amount of time, it blocks your computer until the break timer runs out, so you are forced to step away.
It is only one small part of preventing of glowing your mind and avoiding overwork.
I believe productivity also requires rest. Give your mind the break it deserves every now and then.
