# 마이케이티 vs CJ ONE

The clearest difference is rating: 마이케이티 at 4.3 against CJ ONE's 3.5. 마이케이티 also leads on ratings volume (563 vs 37). CJ ONE's advantage is review sentiment (71% vs 38%). On price, update cadence, ads and in-app purchases there is nothing between them.

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

마이케이티 holds the better App Store score, 4.3 against 3.5. That said, the two scores are not equally well evidenced: 마이케이티 has 563 ratings behind it against 37, so its average is the more settled of the two. Written reviews complicate that: 38% of 마이케이티's written reviews are positive against 71% of CJ ONE's, so the app with the better star average is not the one people write more warmly about.

마이케이티 ships an update every 2 months, CJ ONE monthly. The most recent releases landed on October 24, 2026 and October 23, 2026 respectively.
