Clock

Clock is an open-source Android application based on AOSP that combines alarms, clocks, a timer, and a stopwatch. It is designed as a privacy-conscious time utility and does not use internet permission, so it operates entirely offline. The application is suitable for Android users who need date-specific alarms, time displays, and basic timing tools without an online connection.

Alarms can be set for a specific date, given a custom title and ringtone, duplicated, or deleted with a swipe. Ringtones can be selected for individual alarms or played randomly, and alarms can be dismissed or postponed by flipping or shaking the device. The power and volume buttons can also be used to turn off or postpone an alarm. On some Snapdragon devices, an alarm may trigger while the device is switched off, although this may not work on some devices even when the com.qualcomm.qti.poweroffalarm system app is present.

The application provides digital and analog clock styles, home-time display while traveling, and time displays for many cities around the world. It includes a timer and stopwatch, with an option to share stopwatch results with contacts. Its appearance can use a light, dark, or system theme, including an AMOLED mode for the dark theme, and it supports a customizable interface, screensaver, and widgets. Clock also supports quick settings tiles on Android 7 and later, dynamic colors on Android 12 and later, Material design, and backup and restore of application data, except for custom ringtones.

As an Android entry in the Time & Calculators category, Clock fits devices where alarms, world times, timers, and stopwatches are commonly managed in one application. MirrorNest distributes the official build directly from its own storage and scans it for malware before publishing.
