Known issues

  • Immense memory consumption: If you open immense files, you get immense memory consumption. That’s logic. Usually, Xournal++ Mobile takes twice the file size plus around 50MB for itself.
  • But why does it take twice the memory?: No idea. ¯\_(ツ)_/¯
  • The snap does not start on Linux when using wayland: Please set the environment variable DISABLE_WAYLAND=1 before you start Xournal++ Mobile.

Linux is perfectly supported by Xournal++ Mobile and you can get prebuilt binaries above or install from Snap Store.

Windows is supported and tested too, but there are unfortunately no prebuilt binaries available. Execute the following commands to build them yourself.

flutter channel master
flutter upgrade
flutter config --enable-linux-desktop # or --enable-macos-desktop or --enable-windows-desktop
flutter run -d linux --no-sound-null-safety # or macos or windows

Colors and Typography


Our primary color is the Material DeepPurple. I simply prefer a colorful application over an old-fashioned gray GTK+ application.
