As exciting as iOS 7 is all on its own, what's even more exciting is what developers are, and will be, doing with it. A few cases in point: Vesper, Party Monster, and WeddingDJ. First, Dave Wiskus has an incredibly in-depth look at the design process and thinking behind Vesper 007. From the Vesper blog:

Rather than merely slap a fresh coat of paint on things, we wanted to take the same approach we did with 1.0 and really think through the state of iOS. Which decisions did we agree with? What did we think still needed improvement? Here are some notes on how that process worked.

The Weighted Companion Cube bit is especially charming.

Meanwhile, Allen Pike has posted a look at the redesign process for Party Monster and WeddingDJ. From Steamclock Software:

We started with the two app icons. Icons are a great canvas for experimenting with new design language, and having them early got our old photorealistic icons off of our home screens as soon as possible. The WeddingDJ icon’s shape turned out to feel quite comfortable on iOS 7, so Justin here at Steamclock took that layout and re-rendered it in a more modern style.

The previous Party Monster icon required a more thorough redesign. The photo-realistic 3D renders we used in the original icon were fun, but they didn’t provide enough structure for a vector-style icon. I did more symbolic take on our horned disco ball for the new icon, and to maintain the playful character I brought up the saturation and redness of the purple.

It's clear that what Apple did with the built-in iOS apps was meant to be just that - what Apple did. They show clarity, depth, and deference, but in many different ways. Developers need to think what best suits their apps, given this new world, its new possibilities, and new constraints.

There have been several breathtaking iOS 7 updates already, and some amazing new apps. I can't wait to see what's next.
