# CJ ONE vs 이마트

The clearest difference is rating: 이마트 at 4.0 against CJ ONE's 3.5. 이마트 also leads on monetization model (ad-supported vs free with in-app purchases). CJ ONE's advantage is review sentiment (71% vs 55%). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

이마트 holds the better App Store score, 4.0 against 3.5. Both are backed by a comparable volume of ratings — 37 and 41 respectively. Written reviews complicate that: 71% of CJ ONE's written reviews are positive against 55% of 이마트's, so the app with the better star average is not the one people write more warmly about.

CJ ONE ships an update every 5 weeks, 이마트 every 6 weeks. Both last shipped on November 6, 2026.
