Description

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".

改善のお願い

Apple Watchのモジュラー文字盤にて、コンプリケーションを「Month」に設定した際、文字のサイズが小さすぎる問題が発生しています。 「Month (Start on Monday)」に設定すると正常な文字サイズで表示されます。他の項目は全て正常なサイズなのですが、「Month」に設定した場合にのみ文字が極端に小さく表示されます。 文字が潰れてしまって読みにくく、見た目も良くないため、修正していただけると幸いです。 別途、メールにて比較用の写真を添付して送信いたしましたので、ご確認のほどよろしくお願いいたします。

언어설정 영어밖에 안되는듯..참고하셈

やはり韓国人としては言語設定ができなくて英語しかないのが残念。それ以外は大満足。

최고의 워치 어플리케이션

워치페이스에 1칸 모듈러 자리에 1달 달력 컴플리케이션을 놓을 수 있는 어플을 찾아다녔는데 제가 원하던 바로 그 어플입니다. 가격도 착하고 워치페이스에 놓을 수 있는 컴플리케이션 종류도 매우 많습니다. 강력히 추천드립니다!

휴일표시도 해주세요

딱 내가 원하던 기능이 시계 일부에 전체 풀캘린더를 표시하는 기능이라 이것때문에 애플워치를 다시 착용하기 시작했으나, 공휴일과 임시공휴일을 일요일처럼 빨간색숫자로 표시하는 기능이 아직 없어서 반쪽짜리라고 할수있을듯합니다. 그 기능만 들어가면 500원이 아니라 5천원 5만원이라도 내고 쓸텐데요

좋운데 제대로 작동을 안해요

미리알림과 캘린더가 많아서 그런건지 다시설치해도 앱첫화면에서 먹통이됩니다
