I really like the Bedtime Mode that Android has as a part of Digital Wellbeing. At a specified time, it will turn the screen grayscale, dim the wallpaper, etc.
Is there an equivalent setting or app for Windows? Bonus points if you know of a Linux equivalent too.
there’s a GNOME extension called Bedtime Mode that adds a quick setting to turn the screen grayscale: https://extensions.gnome.org/extension/4012/gnome-bedtime/
