- 📦Mugen Clock updated to version 5.81Your Home Screen widgets can now show the time set in Time Adjustment!
【Time Adjustment for Widgets】
Time Adjustment in Settings now has an "Apply to Widgets" switch. Turn it on, and your Home Screen widgets show the time and date with the same adjustment as the Mugen Clock screen. Set the clock 10 minutes ahead, and your widget runs 10 minutes ahead too — all without changing your iPhone's own clock.
Widgets also change to the next minute at the same moment as the app. The switch is off by default, so your current widgets stay just as they are.
This feature started with a request from one of our users. Have an idea of your own? We'd love to hear it through the app.… more - 📦Mugen Clock updated to version 5.80アラームをより安心してお使いいただけるよう、お知らせを追加しました。
【ライブアクティビティがオフのときのお知らせ】
OSの設定で無限時計の「ライブアクティビティ」がオフになっていると、アラームが正しく鳴らないことがあります。オフのときはアラーム一覧の先頭でお知らせし、そこから設定画面を開けるようにしました。
お気づきの点があれば、アプリ内のお問い合わせからお気軽にお寄せください。 - 📦Mugen Clock updated to version 5.79日付を和暦で表示できるようになりました！
【和暦での日付表示】
カスタマイズメニューの「日付・天気」で「和暦で日付と曜日を表示」を選ぶと、「令和8年11月4日 水曜日」のように元号を使って日付を表示します。時計画面に加えて、ストップウォッチ、タイマー、ホーム画面のウィジェットにも反映されます。小サイズのウィジェットでは「令和8年11月4日(水)」と表示します。
ご要望をもとに追加した表示です。ほかにも欲しい表示があれば、アプリ内のお問い合わせからお寄せください。… more - 📦Mugen Clock updated to version 5.78iPhone Duoに対応しました！
【閉じたときの外側の画面】
外側の画面の角にあるカメラを避けて、時計がすっきり見えるように配置を調整しました。縦向きでは、上部のボタンをカメラの横に並べ、時計は画面の幅いっぱいに表示します。横向きでも、ボタンや日付・天気の表示がカメラに重なりません。カスタマイズメニューもカメラにかからない大きさで開き、タイマーやストップウォッチも外側の画面に合わせて表示を整えました。
【開いたときの内側の画面】
広い内側の画面では、iPadと同じレイアウトで時計を大きく表示します。画面の角の丸みに合わせて上部のボタンと画面の端との余白を調整し、どの向きでも落ち着いて見えるようにしました。
カメラの位置やそれぞれの画面の形に合わせて、時計画面のレイアウトを一つひとつ確かめながら仕上げました。iPhone Duoで気になる点を見つけたら、設定画面の「iPhone Duoに関してのお願い」からお知らせください。最優先で対応します。… more - 🔎Mugen Clock reached Top 10 for “clock”#6 in Turkey search · popularity 70
- 📦Mugen Clock updated to version 5.77We’ve improved the clock screen layout.
【Better Layout When Rotating Your Device】
Fixed an issue where rotating between portrait and landscape could shift the alarm date and time, causing it to overlap buttons or clock digits. Your upcoming alarm now stays correctly positioned when you change orientation.
If you notice anything else, please let us know through the in-app support section.… more - 🆕Mugen Clock first spotted by AppInsider#47 in Top Free · Utilities · Japan
- 📦Mugen Clock version 5.76See your upcoming alarms and chimes right on the clock!
【Your Next Alarm or Chime at a Glance】
Upcoming alarm and chime times now appear in your clock’s font and color. Choose whether to show each one, and tap its display to open the corresponding settings when controls are unlocked.
【Help Checking Your Alarm Settings】
The app now lets you know if it confirms that an enabled repeating alarm is not set correctly on your device. Follow the message to set the affected alarm again, or contact us by email if the issue persists.
【Refined for iOS 27】
We’ve reviewed how the app starts and displays its screens, tested it on iOS 27, and fine-tuned the experience. Vertical brightness gestures are now more deliberate, helping keep them separate from horizontal clock swipes.
We’ll keep refining Mugen Clock. Share your feedback through the in-app support section.… more - 🆕Mugen Clock released on the App Store

Review momentum
82/100
faster than 95% of Utilities apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
