A little Korean word clock for your desk. Hangul Moment displays the time in Hangul with a retro flip clock. Read Korean time on your Lock Screen, or add a clock and daily calendar side by side in StandBy. • Three app themes: Cream, Mono, and Retro Green • A two-line Korean word clock for your Lock Screen • A Korean word clock and daily calendar for StandBy • Four widget looks: Cream, Mono, Retro Green Electronic, and Retro Green Dot • Adjust date, seconds, text size, dimming, flip animation, and sound • Portrait, landscape, and keep-awake while using the app The clock follows your iPhone's local time. Time and dates appear in Korean; menus and guides support English, Korean, and Japanese. All clock features work offline, with no in-app ads or account required. StandBy requires iOS 17 or later. Add the widgets yourself; iOS manages their update timing. “Share Usage Information” is off by default. Only when enabled, Firebase analyzes active clock time, five-active-minute milestones, themes, display settings, widget setup observed by the app, widget guide opens, and app opens through the widget URL. It is separate from advertising tracking and can be turned off at any time. Only if you allow tracking, Meta and TikTok receive data to measure advertising performance. Declining leaves all clock features available. Privacy policy: https://gring2.github.io/retro-korean-clock/en/#privacy Support: pjw6454@hotmail.com With usage sharing enabled, open the updated app once on your iPhone. Home Screen and StandBy clock/calendar widgets and the Lock Screen clock can then send activity signals through Supabase to Firebase during refreshes while the app is closed. The aim is one signal per app instance, UTC day, and widget type. These signals do not measure impressions, viewing time, or exact active user counts. You can turn sharing off at any time in settings.

Verdict
The clearest difference is in-app purchases: Hangul Moment at none against Donut timer's 1. Hangul Moment also leads on update cadence (every 3 days vs every 4 weeks). On price, ads, device support and iOS requirement there is nothing between them.
