Clock is one of the original apps that shipped with the original iPhone back in 2007. A world clock, an alarm clock, a stopwatch, and a timer. It lets you keep track of when it is no matter where you are or who you need to contact. It wakes you up and makes sure you don't leave anything in the oven long enough to burn. It lets you keep track of your laps or endurance. It makes sure you rest just the right amount of time between sets.

While Clock stayed iPhone and iPod touch-only for a long time it debuted on the iPad with iOS 6. And it came with a design right out of the Swiss Rail. Apple settled up but also ditched the look a year later when both iPhone and iPad versions got their iOS 7 redesign.
