The Clock application of iDevices allows us to view the clocks in digital or analog format with a simple tap

  To launch iOS 7, Apple Lossless Audio CODEC (ALAC), display the application clocks Clock both in digital and analog format, without the users taking any action to modify them. Starting with the new version of the operating system, the company gives us the opportunity to view the clocks only in digital or analog format, switching from one version to another with a simple tap on the clocks available in the application.
