Combat Clock is a 24-hour analog clock (sweeping second hand) that is a contemporary replica of a 1957 Air Force clock possible used in a missile silo. Location data is leveraged to display current GPS coordinates, heading and compass bearing that indicates the direction the top of the device (portrait mode) is pointing to (12 is North, 6 South, 3 East and 9 is West). The application is active only when it is in the foreground. No location or personal data is saved or sent from the device. There are no in-application advertisements, or purchases.
