iPhone Screen Time test: What’s your number? (And what you should be doing about it)

How much time do you spend on your phone? (Dreamstime/TNS)

Need a new game to keep people amused at the office? Try this: Ask your co-workers to show you their screen time. 

Ever since Apple rolled out the iOS 12 operating system a few months ago, the new Screen Time app has been tracking time spent with iPhones – specifically, whenever the screen is on. The app lurks quietly in the background, taking note of those scrolls through Instagram that soothe your train commute. Your late-night Twitter habit and the text fight you had with your sister? Add those to the damning total.
