Kronometer is a stopwatch application built for the KDE Desktop Environment.
Kronometer is free software and it’s released under the GPLv2 license.

Kronometer’s main features are the following:

  • Start/pause/resume the stopwatch widget
  • Laps recording
  • Lap times sorting
  • Reset stopwatch and lap times
  • Time format settings
  • Times saving and resuming
  • Font and color customization
  • Lap times export

Kronometer is hosted on the KDE Extragear Utils sub-module. The git repository is located here and is also quickly browsable here, while the old github repository is freezed at the release 1.0.0.


  • Kronometer latest version: 1.4.2
  • Source code: kronometer-1.4.2.tar.xz
  • SHA256: 284c0dfb66afdb38c7d710a993ff874ef13b2df18863adce156f70cdfe0b9df1

Older versions are available in the kronometer downloads page.


Arch Linux

$ yaourt kronometer

The PKGBUILD is available here.
The installation should work also in Arch-based distro like Manjaro.

Chakra Linux

$ ccr -S kronometer

The PKGBUILD is available here.

Compile from sources

There following installation instructions are distro-agnostic, i.e. they should work on all the Linux distributions.

  1. Download the latest source files archive from the link above
  2. Extract the archive in your preferred directory
  3. Open a terminal in this directory and run the following commands:
$ mkdir build && cd build 
$ cmake -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix` ..
$ sudo make install

Now you should have kronometer installed under /usr/bin and it should be available under the Utility entry in your KMenu.
If not, try to reboot your pc and now kronomoter should be in your KMenu.

Most KDE distro should already provide the necessary software dependencies: kdelibs, cmake, make, automoc and gcc-c++.
Some distro (e.g. Sabayon) might not provide automoc by default, so it must be installed before kronometer installation.

Installation tested successfully on:

  • Gentoo
  • Arch Linux
  • Chakra Linux
  • Sabayon Linux (need to install automoc)
  • Opensuse (need to install kdebase4-workspaces-devel)
  • Linux Mint (need to install kde-workspace-dev)

Please let me know if you managed to install kronometer successfully on you distro, and I will add it to this list.
