4.3.1: May-14-2026, All Platforms — Line-Wrap Title in Event Dialogs

4.3.1 is a minor patch release for all platforms that includes a single enhancement: the Title field of event edit and add dialogs now line-wraps its text so it is easier to view on narrow displays. Title is still meant to be a short, one-line summary of an event, but the new wrapping better accommodates constrained screens on phones and small windows on PCs. See the before and after screenshots.

To maintain uniform spacing, Title is still displayed as a single line that is scrolled instead of wrapped in both the Month screen and event-list dialog. Because of this, any explicit newlines added to a Title are automatically converted to spaces on input to avoid run-together in Month and event lists. Title is line-wrapped only in event dialogs, to avoid cumbersome cursor navigation for a user-input field. This change has no impact on prior screenshots, videos, or documentation.

4.3.0: May-1-2026, All Platforms — One-tap Copy/Cut, Save Button, Etc.

This update has both new functionality and improvements, and is a recommended upgrade for all users on all platforms. It includes a one-tap Copy/Cut mode for faster event repeats and moves, a top-of-screen save button for easier change checks and saves, Paste and Quit options for convenience, and more. Videos and screenshots were updated for 4.3.0's changes.

The following list details 4.3.0's changes, with items that apply to all platforms unless labeled otherwise:

New one-tap Copy/Cut mode speeds event repeats/moves
In this app, event repeats and moves take the form of a copy or cut in the event dialog followed by a longpress paste on a day number in the Month screen. To make these actions quicker, the new Settings-screen item One-tap Copy/Cut eliminates a step for both. Specifically, this mode: The combined effect avoids one tap whenever you repeat or move an existing event.

This new mode is enabled by default because event repeats and moves are both very common operations. It can be disabled in Settings, however, because it sacrifices utility for Copy—events cannot be edited further after the copy without re-opening them with a tap, though this is a rare use case; and it removes a verification guardrail for Cut—inadvertent cuts proceed silently, though the event dialog closes and the cut event is saved in a buffer and may be pasted back into the still-highlighted day.

New top-of-screen button flags changes and speeds saves
Calendar saves are also common operations in this app. Unsaved calendar changes were previously indicated by a * preceding the Save Calendars action in the main menu. This is still present but requires opening the menu to check for changes that may require a save.

To avoid a step, an additional, transient, and more prominent icon button is now displayed at the top left corner of every screen when a save is advised. This button has an icon that resembles a disk drive and appears whenever there are unsaved calendar changes. Tapping it saves all calendars with changes just like the main menu's save, and removes both button and menu indicator until the next change. The net effect better alerts you to unsaved changes and avoids one menu-open tap or pull per check or save.

New Paste button in event-list dialog adds convenience
The event-list dialog, opened on single-tap of the number of a day with events, has gained a Paste button to paste the most-recently copied or cut event on the tapped day. This button is a redundant convenience: it works the same as a longpress on a day's number, which is still available and is required for pastes in days without events. You may, however, find Paste to be useful if you inadvertently single-tap a day number, if not easier in general. As before, follow up with Save to add an event pasted by either longpress or Paste.
New Quit App action in main menu boosts speed and safety
The main menu has gained a Quit App action that closes the app when selected but first verifies the close if there are unsaved calendar changes. On PCs, this is the same as clicking the window-close ("x") button, but on Android, it offers a way to exit that may be quicker than closing the app in Recents (e.g., by Back plus Recents swipe) and is safer than Recents closes that ignore unsaved changes. While redundant with other closes, this action provides an alternative that's platform-neutral and safe.
Event-Edit dialog's Save now does nothing if no changes made
In the event-edit dialog, the Save button now more intelligently checks for field changes and does not flag a calendars change if no fields have been modified. Hence, Save for edits is equivalent to Exit when no changes have been made to the event, and simply closes the event.
Etcetera
Lesser changes include a repair for the display of calendars that fail during saves, a rare potential bug never seen or reported.

4.2.0: Apr-1-2026, All Platforms — Cut, Android Back, Text Styling, Etc.

This update has both new functionality and fixes, and is a recommended upgrade for all users on all platforms. It includes a Cut button that speeds event moves, pause instead of close on Android Back, faster search-result scrolls on PCs, and GUI improvements and bug fixes.

The following list details 4.2.0's changes, with items that apply to all platforms unless labeled otherwise:

New Cut button in event-edit dialog speeds event moves
The event-edit dialog, opened on event taps, has a new Cut button. This button acts like a Copy + Del (delete) combo, but saves one tap in the common event-move use case. It's still confirmed as for Del, but it avoids having to also tap Copy for a later longpress paste of the cut event.

As part of this addition, the event-edit dialog's former Update, Delete, and Cancel were shortened to Save, Del, and Exit, respectively, to save horizontal space, and Create became Save in the event-add dialog to match. Deletion (now Del) was retained to allow you to remove without erasing a prior copy, and Copy is still available for event repeats via pastes.

Android: pause instead of closing on Back
On Android, this app now enters paused mode instead of closing altogether, when the Android Back button or gesture is used in the main Month screen. In paused mode, the app remains in memory and may be quickly resumed in Android Recents without calendar reloads. This is the same state that arose formerly for Android Home and Recents taps while using the app.

Pause mode is convenient but consumes memory. To close the app in full and reclaim its memory for use by other apps, close the app in Recents as usual (e.g., by Back tap and Recents tap and swipe, or by Recents tap and swipe). Android Back is also no longer ignored when a dialog is open: the dialog simply stays open during the pause.

Important: Back no longer warns about unsaved calendar changes, because it no longer closes the app. As before, the app has no way to warn about unsaved changes when it's closed in Recents, so take care when performing such closes: check the changes indicator at the main menu's Save Calendars (or the top-of-screen indicator in 4.3.0+). On PCs, the app still warns about unsaved changed on close requests, but this same caution applies to PC forced closes. There is no auto-save in this app because it could preclude abandoning unwanted changes.

Stylize more text in dialogs, Help, and About
There has been additional styling to the text of both dialogs and the Help and About screens, including colors that better call out salient points. For example, cautions now appear with bold red to alert users, and orange text replaces underlines where appropriate. Colors used are all readable in both light and dark themes.
Move confirmations Cancel to the right
For consistency with other cancel and exit buttons, the Cancel button in action confirmation dialogs has been relocated to the right side of the dialog. This commonly crops up on event-edit Cut, Del, and Quit with changes.
Android: improve path display in Settings
On Android, calendar paths displayed in the Settings screen are displayed with the same friendlier format as in load and save confirmations: replacing hex escapes returned by Android (%3A and %2F) with their equivalent characters (: and /). These paths are content URIs required by Android's proprietary Storage Access Framework, not portable POSIX pathnames.
PCs: boost scrolling speed for Search results
On Windows, macOS, and Linux, the scrolling speed of the Search screen's results list has been increased to be the same as that of the Help and About screens. This is particularly useful when there are many results and you want to skip ahead to another month or year. For finer-grained control of scrolls, use a press-and-move gesture. Android scrolls were already fast.
Fix: use default color for unknown categories in event-edit dialog
This app no longer aborts when users tap an event whose event category name is not a valid color name. Such unknown category names are now simply colored with the default event color when opened in the event-edit dialog, as they already were in the Month screen. Although category names in new events added in the app can be color names only, this use case can arise when using calendars created in other calendar programs, including unconverted Frigcal 3.0 calendars.
Fix: fill empty numeric fields with defaults in Settings
This app no longer aborts when users tap Save in the Settings screen after leaving a numeric input field empty there. Instead, such empty fields are filled with their preset defaults post edits, and an info popup alerts the user. These fields also now restrict their inputs to digits 0-9, but they can be left empty after user edits.
Retake screenshots and add a video to demos
All screenshots were updated to reflect the UI changes noted above, and a video shot on Android was added to the app's demos library.

4.1.0: Feb-12-2026, All Platforms — Save *, Stats, Calendar Prefill, Etc.

This update includes both new functionality and fixes, and is a recommended upgrade for all users on all platforms:

New calendar changes indicator in menu for saves
The Save Calendars option in the main menu now shows a * prefix whenever there are unsaved calendar-file changes. This lets you check for changes by simply opening the menu to look for this indicator, instead of either running a save to trigger the no-changes message or closing the app to trigger the unsaved-changes warning. (See also the later top-of-screen changes indicator button of 4.3.0).
New calendar statistics display
In the confirmation dialog shown after calendar loads and saves, a new small report gives the total and per-calendar number of events in the calendar folder's files. This can be used to verify calendar contents. Scroll the dialog's message to see all the details where needed.
New calendar-field prefill for events
When adding a new event, the Calendar field of the event dialog may be now prefilled with a sole or default filename, to help you save a step. This works by trying the following options in turn:
  1. If there is just one calendar file, use it to prefill calendar in the event dialog, and do not open a calendar-selection list on calendar-field taps.
  2. If a default calendar file has been set in the new Default calendar field of the Settings screen, and that default file exits, use it to prefill calendar in the event dialog, but also open a calendar-selection list on calendar-field taps for other choices.
  3. Otherwise, do not prefill calendar in the event dialog, and open a calendar-selection list on calendar-field taps for a required choice (this was the prior 4.0 behavior)

The net effect avoids calendar-selection steps on event adds if you either use just one calendar or store most events in a calendar set as the default in Settings. The Settings default is not applied to events copied and pasted into other days, because pastes should initially retain all field values; simply tap to select a different calendar if desired. Calendar prefills also do not count as a change for verification when closing the edit dialog.

Colorized category name
The category name in the event dialog is now colorized. Given that category name is simply a color name chosen from a list of predefined colors, it makes sense to colorize it in the dialog to reflect and preview the overscore bars of events in both the Month screen and event-list dialog.
New combine-calendars tool
There is a new tools script, combine-calendars.py, which may be run to combine multiple calendars into a single calendar. It creates a new ICS file in a new folder that contains all the events among all ICS files in an existing calendars folder. If you've used multiple calendars in the past, this can simplify some operations going forward, including the prior update's prefills. Read more here and look for this tool both online and in the tools folder of PC installs, and read its top-of-file docs for usage info.
Fix: AppleDouble skips
When loading calendar files, any ._calendar.ics files in the calendars folder are now skipped. These files, known as AppleDoubles, can crop up when manually copying calendars to a FAT or exFAT drive on macOS for use on other platforms. They do not contain calendar content and it is harmless to skip them. They were formerly skipped with failure messages in load-confirmation dialogs, but are now ignored silently.
Fix: event-scrolls reset
The day cells in the Month screen are now automatically reset to be unscrolled when navigating to a different month or loading calendars from a different folder. Formerly, scrolls of days' events in a prior month were retained after navigations and loads, even though they were irrelevant to new months' events.
Fix: closes during dialogs on PCs
On PCs only, calendar-changes warning dialogs no longer keep accumulating if the window-close button is pressed while this dialog is open. To avoid this and other close perils, window-close button presses on PCs are now ignored if any popup dialog is open, including the calendar-changes warning as well as the field-changes warning on event dialog closes. Navigate out of open dialogs to close the app on PCs, just like you do on Android (until 4.2.0's pause on Back). Android has no window-close button.

4.0.0: Jan-30-2026, All Platforms — New App's Initial Release

Frigcal 4.0.0 is a fully redesigned calendar app, with a new UI, seamless Android support, and broad PC portability. Like its predecessors, it still stores calendars in ICS files that maximize transparency and portability. This first release is thoroughly vetted and functionally complete and 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 and demos. 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's 4.X line 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 the Tkinter library 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 (see the former guide for running 3.0 on Pydroid  3).

The new 4.0.0 Frigcal uses the same ICS files as the legacy Frigcal and some of its calendars-processing code but uses Kivy library and stack 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.
