Verdict
The clearest difference is rating: KB제로페이Biz at 5.0 against MobileTmoney's 3.1. MobileTmoney's advantage is update cadence (monthly vs every 21 months) and ratings volume (178 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
KB제로페이Biz holds the better App Store score, 5.0 against 3.1. That said, the two scores are not equally well evidenced: MobileTmoney has 178 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 18% of MobileTmoney's written reviews are positive against 0% of KB제로페이Biz's, so the app with the better star average is not the one people write more warmly about.
MobileTmoney ships an update monthly, KB제로페이Biz every 21 months. The most recent releases landed on October 26, 2026 and October 14, 2026 respectively.
