The beginning of this year, I was using my iPhone to browse new titles on Amazon when I saw the cover of “How to Break Up With Your Phone” by Catherine Price. I downloaded it on Kindle because I genuinely wanted to reduce my smartphone use, but also because I thought it would be hilarious to read a book about breaking up with your smartphone on my smartphone (stupid, I know). Within a couple of chapters, however, I was motivated enough to download Moment, a screen time tracking app recommended by Price, and re-purchase the book in print.Early in “How to Break Up With Your Phone,” Price invites her readers to take the Smartphone Compulsion Test, developed by David Greenfield, a psychiatry professor at the University of Connecticut who also founded the Center for Internet and Technology Addiction. The test has 15 questions, but I knew I was in trouble after answering the first five. Humbled by my very high score, which I am too embarrassed to disclose, I decided it was time to get serious about curtailing my smartphone usage.
