About CalCs - Calendar ComplicationsStorefront description supplied by Apple.

CalCs (short for "Calendar Complications") is a watchOS-only app that provides various complications related to the calendar.

--Important Notes--

The features built into the main body of this app are limited to listing events/reminders & displaying a monthly calendar.

All other features are provided through complications & the Smart Stack.

●If you download CalCs from the iPhone App Store, due to synchronization issues between the iPhone & Apple Watch, CalCs may not appear on the Apple Watch.

According to Apple's specifications, watchOS-only apps cannot be re-downloaded from the App Store app on the iPhone.

Therefore, please use the App Store app "on your Apple Watch" & follow the steps below to re-download it.

・Scroll to the bottom→"Account"→"Purchased"→"CalCs"→re-download

Key Features

●Supports a variety of complications such as date display, events/reminders display, & monthly calendar display

・Date Display

Displays the current date in various formats.

・Event/Reminder Display

Displays events/reminders synced with your iPhone.

You can choose whether or not to include all-day events.

・Monthly Calendar Display

Displays the monthly calendar in various formats.

You can choose to start the week on Monday.

Supports holidays in some areas.

*Holiday data depends on external APIs & may be incomplete.

Only Modular Duo supporting models (Series 7+, not SE series) can show a month calendar using 2 large rectangles. Other models can show it in 1, with smaller font.

●In the main app, events/reminders, & the monthly calendar are displayed

Tapping the complication opens the app, where you can view the list of events/reminders synced with your iPhone, as well as the monthly calendar.

*Only incomplete reminders are displayed.

*The app currently does not have functionality to add, edit, or delete events/reminders, nor to mark reminders as complete.

●Minimal Setting Options

To avoid complicating settings on the small Apple Watch screen, the settings only allow you to select which calendar/reminder lists to display.

*Notes

・The corner complications, circular complications, & large rectangular complications are supported only on Apple Watch Series 4 & later, so CalCs is not guaranteed to work on Series 3 or earlier models.

・Due to the limitations of watchOS complication display updates, complications may not immediately reflect changes when the date changes or after events or reminders are added or edited on the iPhone.

・After placing a complication for the 1st time, it may take some time for it to actually appear.

・If the complication is not updating, try tapping the complication to open CalCs, as this may refresh the data.

・If the complication is not updated even after launching CalCs, the issue may be resolved by 1 of the following methods. Please try them.

1.Restart both your iPhone & Apple Watch.

2.Force restart CalCs

①With CalCs open, press & hold the side button.

②When the screen for emergency call & power off appears, press & hold the Digital Crown.

3.Reinstall CalCs

①Press the Digital Crown to display the app list.

②Press & hold CalCs, then tap the × button to delete it when it appears.

③Launch the App Store app on your Apple Watch.

④Scroll to the bottom→"Account"→"Purchased"→"CalCs"→Re-download.

・If the complication does not update after force quitting & restarting CalCs, try restarting both your iPhone & Apple Watch, as it may resolve the issue.

・If event information is not displayed on the app's main event/reminder list screen or in complications, it may be because full access to the calendar has not been granted.

The issue may be resolved by following the steps below to re-enable full access permission to the calendar. Please give it a try.

①Open the "Privacy & Security" section in the iPhone Settings app & tap "Calendars".

②Change CalCs' calendar access to "None", then select "Add Events Only".

③When you open CalCs, you will be prompted to grant full access, so tap "Allow Full Access".
