One of the major criticisms of previous iOS versions is the heavy use of skeuomorphic or real-life elements, such as the torn pages in the Notes app or the leather trim in the Calendar app.
The new flat design takes away all that clutter and adds a more colourful palette.
I like the fact that there is a greater use of white space with translucent layers in iOS 7's interface. The typeface used is thinner but it blends in perfectly with the new design scheme. Overall, I think iOS 7 is the most elegant iOS so far.
While there are no widgets in iOS 7, you can see the second-hand of the default Clock app icon moving with the hour and second hands corresponding to the actual time.
For the first time, you can use dynamic wallpapers in an iOS device. Only seven dynamic wallpapers are included and they are essentially different colours of the same bubble design.
For those resistant to change, fret not. The basic structure of iOS 7 remains unchanged, so veterans will have no problems changing settings.
The Control Centre
One major gripe I have with the previous iOS is that I have to tap through two menus to turn on Bluetooth or Wi-Fi. But with iOS 7, I just need to swipe up from the bottom of any screen to bring up a dashboard known as the Control Centre.
The Control Centre is full of short cuts to the most commonly used controls and apps, such as Bluetooth, Wi-Fi, Do Not Disturb, Airplane Mode, Camera and even Calculator.
There is also an option to turn on the rear LED flashlight to help you get to your seat in a cinema or bring up the timer when you want to, say, cook your instant noodles in exactly three minutes.
Unfortunately, there is no way you can customise the Control Centre. Perhaps, in iOS 8?
