No Longer Maintained

Unfortunately, I am not able to work on Reminduck anymore. It was a fun side project but I no longer use Linux and don't have the time to make sure it keeps working correctly.

If you or someone you know wants to keep the project going, feel free to fork and/or let me know so I can move the ownership of this repo to you (if that's possible). I can also check with the elementary AppCenter/FlatHub if it's possible to change ownership of an existing app.


Download on Flathub


Reminduck is a simple reminder app made to be quick and easy - it focuses on simple or recurrent reminders with set time and date and nothing else.

It's perfect if all you want are simple or daily/weekly/monthly reminders. Anything more than that is not achievable by Reminduck right now - but you can help! Open an issue or a pull request if you have any ideas or requests.

And it quacks.

Built for elementary OS

While Reminduck can run in any Linux distribution, it was built with elementary OS in mind. It runs perfectly on other distributions like Ubuntu, Fedora, etc. though. Download it on Flathub if you want to use Reminduck everywhere!


You can help translating this app with the following steps:

  • Add the language you want to translate to in the po/LINGUAS file (if it's already there, you can skip this step);

  • Then, make sure the translation files are updated:

    cd build
    ninja com.github.matfantinel.reminduck-pot
    ninja com.github.matfantinel.reminduck-update-po
  • Then, update your language file in po folder with your translations. For example, portuguese (pt) translation file is po/pt.po;

  • Some additional translation files can be found in po/extra/ (stuff for the xml and .desktop files)

  • You might want to update these files as well:

    # we're still in ./build
    ninja extra-pot
    ninja extra-update-po
  • Fork this repo, commit to your repo and then open a Pull Request to this one.

Developing and building

If you want to go ahead and compile Reminduck yourself, you'll need the following dependencies:

  • libgranite-dev
  • libgtk-3-dev
  • meson
  • valac
  • libsqlite3-dev
  • gettext

You can install them on elementary OS Juno with:

sudo apt install elementary-sdk libsqlite3-dev

And on other Ubuntu-based distributions with:

sudo apt install libgranite-dev libgtk-3-dev meson valac libsqlite3-dev gettext

Run meson build to configure the build environment and run ninja install to install:

meson build --prefix=/usr
cd build
sudo ninja install

Then run it with:



Reminduck is also available as a Flatpak. To build/install it locally, first you have to install the necessary runtimes:

sudo apt install flatpak-builder
flatpak install flathub org.freedesktop.Sdk/x86_64/19.08
flatpak install flathub org.freedesktop.Platform/x86_64/19.08
flatpak install flathub io.elementary.BaseApp/x86_64/juno-19.08

Then, from the project root:

flatpak-builder --install repo com.github.matfantinel.reminduck.json --force-clean --user

The app should be displayed on your apps list, or you can run it with:
