After release, install GEULGYEOL from the App Store and open it once. The app lets you explore the themes and see how to add widgets.
APPLE / MANUAL
User guide
From installing after release to changing themes, follow the steps for your device.
Add a Home Screen widget
Touch and hold the Home Screen, then choose Edit → Add Widget → GEULGYEOL. Add a medium or large widget. Menu names may vary by OS version.
Choose a widget theme and seconds style
Touch and hold the added widget and open Edit Widget. Choose a theme and numeric (00–59) or word seconds. Changing the theme in the app preview does not change the settings of every iPhone widget you have placed.
Install on Apple Watch and choose a theme
Install the app on your paired Watch and open it once. Scroll vertically or turn the Digital Crown to change themes. Your selection is saved on the device.
Connect Smart Stack
Open Smart Stack with the Digital Crown, then touch and hold to edit it. Add GEULGYEOL’s “Follow Watch Theme” widget (워치 테마 자동 적용). The theme selected in the Watch app appears in the stack according to the system’s refresh schedule.
Check after an update
Open the Watch app once. If a card from an older test build does not appear correctly, remove it from Smart Stack and add it again.
Frequently asked questions
The seconds stop or show “—”.
Word seconds advance each second while the Watch app is visible. Live widget seconds require iOS 18 or watchOS 11 or later, and may show “—” in reduced luminance. WidgetKit manages updates to hours, minutes, dates and themes, so changes may take time to appear.
Can I use it as the built-in Watch face?
GEULGYEOL is a Watch app and Smart Stack widget. It does not replace the built-in watch face or hide or move the system clock.
Do I need an account or internet connection?
The clock does not require a SEROUI account. Theme preferences are saved on your device. Installing or updating the app and sending support emails require a network connection to the relevant service.
