Recently I was testing an app we’re building that didn’t have an app icon yet. I noticed that iOS 7 provided a new placeholder image. That placeholder just so happens to be a pixel perfect version of the new iOS 7 grid, finely tuned at every size. It wasn’t until I saw this grid to scale—directlyfrom Apple—on all my devices that I decided to create a template of my own that appealed to my obsessive nature.
