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.

Verdict
The clearest difference is in-app purchases: 腕力球 at none against K's 1. 腕力球 also leads on device support (3 vs 1) and iOS requirement (8.0 vs 16.0). K's advantage is update cadence (weekly vs every 9 months). On price and ads there is nothing between them.
