On a recent episode of The Talk Show, John Gruber remarked that using the digital crown to zoom into apps seemed gimmicky, or something like that (I’m not going to find a direct quote). And in more than one episode he has, along with his guests, expressed issues with tapping on the tiny icons on the watch face. It just so happens that the hexagonal nature of the app layout provides a great way to make better use of the zoom-to-launch feature.
Just like throwing your mouse cursor into a corner of your screen has been a shortcut to accessing features like your screensaver for decades on the Mac, intentionally placing apps at a corner of your app layout makes it very easy to position them to the center location. A quick spin of the digital crown and you’re launched.
Adopting this mentality for my app layout has made launching my frequently used apps much faster.
