The device in the article is $400 (and obviously requires migrating to a new phone.) Don't get me wrong, it does seem like a decent solution - but for those looking for a lower friction (or lower cost) way to use your phone less, this is my system, which works very well: 1) lock away your phone in a separate box or room away from where you are, 2) make the phone as unappealing as possible (grayscale, disable animations, don't upgrade models, fill up storage so it's very slow), 3) increase friction on the device itself; uninstall any interesting apps and use "one sec" to block stuff in the browser.
With these interventions I went from using my phone for hours a day to using it (most days) only when necessary, and some days not at all. Feels very liberating!
As far as reading goes, I switched back to physical books.
