Over the past week and a half I've been using the app Adobe Photoshop Sketch for iOS with the iPad Pro and Apple Pencil. It's not what I expected. I expected it to be an experience in which the stylus (the Apple Pencil) would be speedy and the app would have simple basics. As it turned out, the Apple Pencil is speedy, yes, but latency is so extremely small it's as if the hardware were made for this app specifically. This goes for the app interacting with the Pencil as well - tapping between brushes and backing up and drawing - all of this felt entirely natural.
