@tatokis is now the new maintainer Posted Jan 19, 2023

Hello alarm-clock contributors and users,

After a long period of being unmaintained, I am thrilled to announce that alarm-clock has a new maintainer: @tatokis!

You may have noticed a recent burst of activity in the project, with lots of improvements, bug fixes, and even a new 0.4.1 release! All of these developments are thanks to @tatokis.

New maintainer

As the original creator of alarm-clock, it makes me very happy to hand over the maintainership to @tatokis. He has already made significant contributions to the code base, including porting the project to Gtk 3, GSettings, GtkApplication, GActions and a more modern CMake build system. All of these improvements should also enable alarm-clock-applet to be packaged in modern Linux distributions. I am confident that the project will thrive under his leadership.

Note: The maintainership was handed over in Nov 2022, but I felt it was appropriate with an official announcement. My apologies for the delay in making this announcement.

Alarm Clock 0.4.1 "Happy New Year" released! Posted Jan 9, 2023

GitHub Release

This release fixes numerous issues and removes all legacy dependencies. The minimum supported Ubuntu version is now 18.04.

Major Changes:

  • The application has been ported to GTK 3, and will thus look slightly different.
  • Old GTK Tray Icon support has been removed. A desktop environment with support for AppIndicators/StatusNotifierItem is required.
  • Alarms have been migrated to GSettings.

Notable Fixes:

  • Many memory leaks (including a massive one while the UI was visible)
  • Alarm labels bouncing horizontally every second
  • Debug messages breaking alarms and timers
  • Compile errors

New Features:

  • Default media players are now autodetected.
  • More media players can be controlled using playerctl out of the box.
  • More system sounds are now added to the list by default.

Full Changelog:


Notes for package maintainers:

Many dependencies have changed and the project is now built with CMake. If available, please build with GConf2 support enabled so that people can migrate any old alarms they might have, even if they built from source previously. If possible, also add playerctl as an optional/recommended dependency; its presence is detected at runtime.

What happened to 0.4.0?

It was meant to be tagged right before the major rewrite/porting work started, however it was tagged at the wrong commit by accident, and is thus now ignored.


Unfortunately, this project is no longer maintained. If you're interested in maintaining Alarm Clock, please get in touch:

Alarm Clock 0.2 released! Posted May 1, 2008

Highlights for this release include: Multiple alarms, different alarm types, repeated alarms and snooze support!

The 0.2 release of marks an important milestone of the Alarm Clock development.


Alarm Clock now supports multiple alarms running simultaneously.

Alarm Clock now distinguishes between two types of alarms: Clocks and Timers. The default type, Clock, will trigger at a specific time of day. The Timer will trigger after a specified amount of hours, minutes and seconds.

Alarm Clock will now allow you to specify at what days an alarm (of type clock) should trigger. No need to activate the alarm before you go to sleep any more!

An alarm or timer can now be snoozed for a specified number of minutes. This only applies for alarms which uses sound notification. Clicking the applet will snooze all running alarms. To clear all alarms, right click the applet and choose "Clear alarms".


Easy to use

Alarms list

Alarm Clock is easy to use - clicking the panel icon will bring up a list of alarms. From there you can add, edit and delete alarms as well as start, stop and snooze them.

Alarm Clock supports two types of alarms: ClockClocks and TimerTimers. The Clock will go off at a specific time of day while the Timer will ring after the specified amount of time.


Edit alarm

Alarm Clock will notify you of an alarm by either playing a sound or starting your favorite music player! You can of course specify which sound you would like to use and whether it should be repeated or not. It’s also possible to specify a custom command to run instead of the pre-defined media players.

A notification bubble will appear when an alarm goes off, just in case you missed the sound.

Alarm notification bubble


Alarm Clock menu

Both alarms and timers can be snoozed - it's as easy as selecting the alarm and clicking "Snooze".

For convenience, the right-click menu of the panel icon provides quick access to snoozing and stopping any beeping alarms.


Alarm Clock is powerful and supports multiple alarms as well as auto-repeatable alarms.
