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.
