Verdict
The clearest difference is rating: KT 멤버십 at 4.0 against CJ ONE's 3.5. KT 멤버십 also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). CJ ONE's advantage is review sentiment (71% vs 38%) and device support (3 vs 1). On price, update cadence, in-app purchases and iOS requirement 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.
KT 멤버십 holds the better App Store score, 4.0 against 3.5. Both are backed by a comparable volume of ratings — 37 and 138 respectively. Written reviews complicate that: 71% of CJ ONE's written reviews are positive against 38% of KT 멤버십's, so the app with the better star average is not the one people write more warmly about.
CJ ONE ships an update monthly, KT 멤버십 every 2 months. The most recent releases landed on October 13, 2026 and October 14, 2026 respectively.
