K-Card Reader is a focused Korean transit card balance checker for iPhone. Tap a supported physical KS X 6924 card with NFC to read practical details such as card family, card number, stored balance, issue date, valid-through date, recent trips, and local transaction history where the card exposes it. It is built for travelers, residents, and anyone who wants a quick way to check T-money, EZL/Cashbee, Climate Card, NAMANE, MOIBA, or K-Cash without hunting through station machines. Saved cards stay on your iPhone for fast review. Pro Mode is an optional $2/year subscription that removes ads, unlocks the hex parsing view, and backs up saved cards plus custom card-face images with your iCloud account. This is an unofficial utility and is not affiliated with transport operators, card issuers, or payment networks. It cannot top up cards, issue tickets, validate fares, or modify card data.

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 K's 1. Hangul Moment also leads on update cadence (every 3 days vs every 9 days). K's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
