Complications are what I miss most when not wearing my Apple Watch, especially when I'm looking at my iPhone lock screen.
I've been thinking about this for a while, but I became acutely aware of it this weekend when I took my Apple Watch off for a couple of hours to see what, if anything, I'd miss. I expected primarily to be annoyed by the iPhone's notifications, having to reach for my phone at every buzz and beep like it was 2014 again. But after repeatedly glancing at my wrist and seeing nothing but wrist, I realized how much I'd come to depend on the highly accessible, hyper-dense information provided by the Apple Watch's clock face complications.
"Complications" refer to any feature on a watch beyond showing the time in hours and minutes. With the Apple Watch, however, they've come to mean something more. That's the advantage of taking wearables from analog and digital to computational. Almost subconsciously, I'd gotten used to subtly turning my arm and remaining almost passively, constantly aware of the weather, my activity progress, my calendar, and more. Then, when I did reach for my iPhone 6 Plus to check a notification, the lack of similar information on my lock screen was notable. That's why I'm hoping Apple considers adding complications to the lock screen in iOS 9.
