Someone on Reddit actually noticed and took the time to do this. Actually, we’ve heard a lot about how Apple uses these squares with rounded-edges. However, someone decided to take a closer look at several of these and compare the iOS 7 grid to Apple’s real world products. It doesn’t seem like a total coincidence.
You can check out more on Reddit. It’s kind of interesting to see how these designs all fit within that grid. It definitely looks intentional once you really take a good look at it all. Regardless, it’s pretty cool to see it. There is probably a bit more of this throughout Apple design, and maybe we just haven’t noticed it. Still, it’s cool to see.
