A01 Support

A01 Silicon Horology is an analog clock with a foreground compass, Moon and daylight dials, second time zone, timers, repeating alarms, stopwatch and Desk & Bedside mode.

Using your clock

Moon, daylight and second time zone

Tap the left subdial to choose Moon or second-zone information and a daylight city. Bundled cities work offline. Use my location needs permission and an Apple place lookup to resolve the time zone. Repeat the lookup after travelling to update the saved place.

Compass

The compass operates while the app is open and requires a compatible sensor. Magnets and nearby metal can affect the heading.

Timer, alarm and stopwatch

Timer and alarm alerts need system alarm authorization. Saving an alarm enables it when accepted; turn it off before editing. Stop the stopwatch before resetting it.

Desk & Bedside

Expand the controls to adjust dimming or keep the screen awake. Tap × to exit.

Home Screen widgets

Widget timing is managed by iOS. StandBy is not currently part of the supported launch experience. Live weather is not provided.
