AlarmClock Deluxe (Wecker, Uhr, Timer, Stoppuhr)

Alarm, clock, timer and stopwatch with advanced alarm tools
New in version 2026.08.001
First public CalVer release (2026.08.001) of AlarmClock Deluxe.

Fork of BlackyHawky's Clock with richer alarm management: fire queue,
progressive snooze, global mute, tags, search/filters, Wi-Fi rules,
JSON backups, Syncthing-friendly exchange, multi-stopwatch, timezone
globe, and more. Location permission is used only to read the Wi-Fi SSID
for optional rules — no internet access.
AlarmClock Deluxe (Wecker, Uhr, Timer, Stoppuhr) (de.huttersoft.mightyalarmclock)
is a fork of BlackyHawky's Clock, itself based on AOSP, released under the GNU
General Public License v3.0 (GPL-3.0).

Does not use the internet permission, and thus is 100% offline.

The location permission is used only to read the SSID of the connected Wi-Fi
network for optional per-alarm Wi-Fi rules. No location data is collected or
sent; the app cannot access the internet.

On top of everything the original Clock app offers, AlarmClock Deluxe adds:

  • A fire queue so multiple alarms firing close together are presented one after another instead of being marked missed;

  • Progressive snooze (each snooze can automatically get longer) plus a manual snooze duration picker;

  • Global mute: silence or vibrate-only every alarm until a chosen time;

  • Naming a new alarm right when it's created;

  • Searching, filtering and extra sorting options for the alarm list;

  • Tags with their own ringtone, automatically used by alarms that don't set one explicitly;

  • Device-wide alarm statistics with a shareable event log;

  • Wi-Fi based rules to automatically enable/disable alarms depending on the connected network;

  • Plain JSON backups (no ZIP) to a folder of your choice, with optional scheduled backups;

  • An experimental "exchange" mechanism to move or share alarms between devices via a shared folder;

  • Multiple named stopwatches that can run in parallel, with runs recorded in the event log;

  • A small rotatable timezone globe on the clock screen showing your selected world cities;



...and the full original Clock feature set:

  • Set the alarms to a specific date;

  • Flip and shake action to dismiss/postpone alarm;

  • Turn off/postpone the alarm with the power button or volume buttons;

  • Swipe to delete an alarm;

  • Duplicate alarms;

  • Customizable alarm title and ringtone;

  • Light, dark or system theme, with AMOLED mode;

  • Customizable interface;

  • Digital or analog clock style;

  • Display home time when traveling, and the time in many cities around the world;

  • Timer and stopwatch included;

  • Customizable screensaver;

  • Modern, customizable widgets;

  • Support for tiles in quick settings (for Android 7+);

  • Backup and restore application data;

  • Material design with dynamic colors for Android 12+;
