It helps me keep my phone usage to a minimum while focusing (at uni or tedious tasks). Itās like muting your tv. When I do have to use it, itās just way less stimulating. And my time on there is absolutely for essential stuff, without having to remind myself so.
Iāve set a shortcut on my iPhone as 3x power button clicks. Boom! greyscale. It kinda works as a physical reminder to focus as well.
