Amazing Developer

If I could give the developer 10 stars I would. I loved the design of the full month calendar complication already, but I asked if he could add a simple complication displaying the date in ISO format. He worked with me collaboratively on the format, and released it shortly after. I am blown away and so appreciative for his work

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。

prtscins様 この度はレビューのご投稿と高評価ありがとうございます。 既にメールにて回答させていただきましたが、他の方の手助けになるかもしれないので、レビューにも返信させていただきます。 大変申し訳ないですが、「Month」のフォントサイズが小さくなってしまう場合があるのは仕様であり、対応は難しいです。 理由を以下に説明いたします。 今月(2026年5月)の場合「Month (Start on Monday)」では5週ですが、「Month」の場合は6週になってしまいます。 そのため表示領域が足りず、フォントサイズを小さくせざるをえません。 5週に収まる月(例えば2026年6月)の場合は、「Month」でも大きいフォントサイズになります。 逆に、「Month (Start on Monday)」であっても6週になってしまう月(例えば2026年8月)では小さいフォントサイズになってしまいます。 常に同じフォントサイズで表示したい場合は、以下の2つの方法をお試しいただけないでしょうか? ・モジュラーデュオ文字盤で、上部に「Month (1st Half)」、下部に「月(後半)」を設置する なお、(SEシリーズや、シリーズ6以前のモデルではモジュラーデュオ文字盤は使えません) ・モジュラー文字盤で「5 Week (Last Week-3 Weeks Later)」、「5 Week (This Week-4 Weeks Later)」などのコンプリケーションを使う (こちらのコンプリケーションはその月全体を表示するのではなく、5週分のカレンダーを可変で表示するタイプになります) 対応できず大変心苦しいですが、上記をお試しいただけたら幸いです。 以上、どうぞよろしくお願いいたします。

Reached out to Dev to add Day abbreviation to header of 5 week full calendar, He quickly added, tks, much better than clockology app as thesr complications do not suck up battery

Events not refreshing on watch face

This is a great idea in theory, however the watch face does not update when a new reminder or calendar event has been added.

FAQ

What does CalCs do?

CalCs provides various calendar complications for your Apple Watch. It allows you to display the current date, upcoming events and reminders synced from your iPhone, and a monthly calendar view directly on your watch face. The main app also offers a list of events/reminders and a monthly calendar.

What are the key features of CalCs?

Key features include complications for date display in various formats, event and reminder display (including an option to include all-day events), and a monthly calendar display. You can customize the start of the week and some regions support holiday displays. The main app provides access to these features in a list format.

How do I install CalCs on my Apple Watch?

Since CalCs is a watchOS-only app, it's best to download it directly from the App Store on your Apple Watch. Navigate to the App Store app on your watch, then go to 'Account', 'Purchased', and find 'CalCs' to re-download it. Downloading from the iPhone App Store may lead to synchronization issues.

Does CalCs allow adding or editing events?

No, the current version of CalCs does not support adding, editing, or deleting events/reminders, nor marking reminders as complete. It is designed for displaying existing calendar information and reminders synced from your iPhone.

What Apple Watch models are compatible with CalCs?

CalCs complications are supported on Apple Watch Series 4 and later. Specifically, the monthly calendar view using two large rectangles is only available on Modular Duo supporting models (Series 7+), while other models display it with smaller font. It is not guaranteed to work on Series 3 or earlier models.
