4.0.0: Jan-30-2026, All Platforms — Initial Release

This first release of the redesigned Frigcal is broadly vetted and functionally complete. It is available in the following forms:

While additional enhancements and repairs are normal and expected to appear over this app's lifetime, its 4.0.0 release is already robust and fully usable on all supported platforms.

For more on the app in 4.0.0 and later, see its user guide. For download links, see the abbreviated Downloads or the complete App Packages.

1.0...3.0: Sep-2014...Dec-2024 — Legacy Version

While this app has an all-new UI and much-improved Android support, its genesis lies in calendar-processing tools hashed out by the legacy Frigcal program from Sep-2014 through Dec-2024, in versions 1.0 through 3.0.

The legacy Frigcal was also created by this app's developer and used Tkinter for its GUI. It worked on all PC platforms as well as Android, but on Android it did not build a standalone app and relied on other apps and their permissions to run its source code.

The new 4.0.0 Frigcal uses the same ICS files as the legacy Frigcal but uses Kivy for its GUI to provide a standalone app on Android that delivers a much more seamless user experience. As before, the new app also works the same on all PC platforms.

Frigcal legacy users: the new 4.0.0 Frigcal's event-color model is not backward compatible with the legacy versions' configuration-files scheme. This is by design, to avoid configuration-file syncs across devices. For help converting legacy color settings to 4.0.0's new model, please see the conversion script.
