For once there is someone here who understands.
I've tested iOS7 started back in June when it launched to the Devs, yes I'm a dev if anyone wants to know and also a graphic designer too.
1) Looks like cheese
There's only two ways to visually design a OS with a "Flat" look and unfortunately iOS 7 doesn't land on A or B.
A) Super flat non-gradient design must be a two colour scheme, such as Windows Phone 7 & 8. Unfortunately it's a waste of a high resolution screen and that explains how the Lumia 900 got away with their mid range specs during their launch.
B) Flat design with gradients that are very subtle with colour change, 3D F/X with minor shadowing and drop shadows, they must be constant across the board. Perfect example would be Skype, eBay, Google and Facebook mobile which had achieved this design aspect properly.
Honestly, iOS 7 looks like a page ripped out of Dora's colouring book, My Little Pony and a essentially a Teletubby phone.Its humanly impossible to have two neon colours that are in a gradient and sitting on a white background to look good. You can't even place bright yellow on white back ground.
An eye for design is something you're born with, enhanced when you take a design course and fully brought to life when you're in the working field
PS:
The Apple Store Icon is Apple's "best" ver so far, it's a "little" better than stock apps. This a big NO NO to go that extreme with gradients of two tones of blue.

The Typography and new ver of Reduced Motion gets a big F grade.
Bolding the fonts in iOS 7 doesn't make the typography of iOS 6 return, the fonts are bolder than iOS 6. It actually makes everything worse by clashing bold & thin fonts with the pencil thin dividing lines and outlines. The entire design layout is right off at this point. The neon gradients, bold white fonts and the white or bright backgrounds is even more "busy" and harder to the eyes, b/c the "kerning" is too close together. First year of college Typography class 101, you would be tossed out of class presenting that type of "mixed" fonts in your design layouts for your assignments.
Reduced motion is now even more whacked. In iOS 7.0-7.0.2 this function was very useful to get rid of the cheesy Lucky Charms parallax F/X and keep the animations running. Now with 7.0.3-7.0.4 you don't have a choice if you want to keep the animation and turn off parallax F/X. Turning reduced motion doesn't help with the speeds, the delays are more noticeable and you still gotta wait with the "new animation" The fade in & out F/X was introduced 10 years ago to hide how slow certain CPUs were running on the old Palm PDA and Treo 600s.
