QuickOffice in KitKat
Here's QuickOffice implemented in KitKat. It makes sense to ship the app with Android, given that Google made it free last month and with Android can ramp up its user numbers and keep Microsoft Office on the outer.
Stopwatch in KitKat
On the left is 4.3.1 and on the right is 4.4. Again, KitKat loses screaming first digit and is more centred. KitKat's stopwatch is visually less cluttered, doing away with the minute and second markers.
Google has made similar design changes in the timer app. In the left is the Jelly Bean's timer, on the right is KitKat's.
