Tldr: Trying out the monochrome/greyscale on my smartphone. I will update the post a few months later so you know how it worked for me.
There are a ton of apps that do something similar. Personally, I don’t find a reason to add another app so here is how I did it. You can find research telling you it will help you use your smartphone less. I will try to reduce my phone usage to an hour of screen time a day. This isn’t an experiment to see if monochrome will be the only factor that will help me reduce my “phone addiction”. For reference, I now have almost 2 hours a day. (checking games, mails, Slacks and etc)
