The result of opening CheckerBoard in a modified shortcut.

Summary

This (hidden) application is usually accessed by powering off the device, then after plugging in a charger, start holding down the volume up button and home button. It is present on all iOS 10.3 devices.

It looks to be sending data to https://idiagnostics.apple.com, however due to certificate pinning, the data being sent is unknown. It is known to connect to AST2, an internal diagnostics web app, for diagnostics.

Other Information

  • It may be worth noting that the time displayed at the top-left (in the case of an iDevice without Airplane Mode) of the screen is Pacific Standard Time, regardless of user preferences.
  • When opened via a Modified Shortcut, it crashes, defaulting to SpringBoard.
