What's New in Atomic Clock PRO

1.8

October 30, 2026

What’s New in Version 1.8 • Support for the foldable iPhone Duo: On the large display, the analog clock sits on one half and the time and date on the other. Tap to swap sides. – New: Desk Clock (Premium). Half-fold your iPhone Duo like a laptop. The clock stands on top, the day and date sit below, and the display stays on. • Numbers on the analog clock (Premium): choose 12, 3, 6 and 9 or all numbers, matching your clock color. • Adjustable date size (Premium): from small to extra large, with a live preview. • New feature: “Reset all settings”. • Bug fixes: In some languages, the date was written with small errors. These are now fixed, along with a few other small, rare bugs.

Response from developer

ご報告いただき、ありがとうございます。ご不便をおかけして申し訳ございません。 こちらで日本語設定を含めiOS 26とiOS 27で確認しましたが、同じ現象は再現できませんでした。 お手数ですが、次の方法をお試しいただけますでしょうか。 1. 画面をタップしてデジタル時計に切り替え、アナログ時計に戻るまでもう一度タップしてください。 2. それでも直らない場合は、アプリを完全に終了してから再起動してください。 それでも針が表示されない場合は、お使いの機種とiOSのバージョンを info@brom-apps.de までお知らせいただけますと、原因の調査に大変助かります。
