# SeoulAuction vs CJ ONE

The clearest difference is rating: SeoulAuction at 5.0 against CJ ONE's 3.5. SeoulAuction also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). CJ ONE's advantage is ratings volume (37 vs 1) and update cadence (every 5 weeks vs every 3 months). On price, review sentiment, in-app purchases and device support there is nothing between them.

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

SeoulAuction holds the better App Store score, 5.0 against 3.5. That said, the two scores are not equally well evidenced: CJ ONE has 37 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 71% and 71% positive.

SeoulAuction ships an update every 3 months, CJ ONE every 5 weeks. The most recent releases landed on November 6, 2026 and November 10, 2026 respectively.
