Alarm, clock, timer and stopwatch with advanced alarm tools
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+;
