I've tried so many things like this over the years and considered Configurator, but my only Apple computer at this point is a corporate Mac that blocks USB access to my phone. It's a great idea, and I'm glad to see it documented.

That said, the biggest shift I encountered in my own phone usage was when I got an Aro box [1]. It's expensive (I got one refurbished), but pretty, and functional, and it has made a HUGE difference in my phone habits. I no longer keep my phone in my bedroom and when I catch myself ignoring those around me in favor of my phone, I can hard cut that off by putting it in the box.

I like the idea of simplifying your phone with software tweaks like this, but I have found the physical separation to be the most freeing, and encourage that if you're interested in freeing yourself from the screen.
