i didn’t want to recommend this without testing it properly. it’s great and works so well i don’t even notice it anymore.
basically it adjusts the brightness of your monitor to match the time of day. theory goes that later at night your body release chemicals when it gets dark that help you sleep. when you’re ‘starin at the glarin’ (just made that up, patent pending) it’s harder to get to sleep.
protip – check the box that resets the brightness gradually over an hour. otherwise it can be instant sepia browning.
