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" and follow the steps below to re-download it.
・Scroll to the bottom → "Account" → "Purchased" → "CalCs" → re-download

●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.

You can perform the following actions in the event/reminder list display:
・Scroll to show events/reminders for the previous month, this month, & the future 3 months.
・Double-tap to switch between showing both events/reminders, events only, or reminders only.
・Long press to scroll to the current or next event/reminder.
・Swipe from right to left to switch to the monthly calendar display.

*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. Please understand.

In the monthly calendar display, you can perform the following actions:
・Scroll to show the previous month, this month, & the future 3 months.
・Double-tap to toggle between Sunday start & Monday start.
・Long press to scroll to the current month.
・Swipe from left to right to return to the event list display.

●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 CalCs is launched & the complication does not update, try force quitting CalCs & restarting it, as this may resolve the issue:
①Long press the side button while CalCs is open
②When the emergency call or power off screen appears, long press the digital crown.

・If you did not grant full access to the calendar on 1st launch, CalCs will not prompt you again.
In this case, you will need to clear the permission on your iPhone & re-grant it through CalCs. The steps are as follows:
①Open the "Privacy & Security" section in the iPhone Settings app & tap "Calendar."
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."
