# CJ ONE vs U+one

The clearest difference is rating: U+one at 4.1 against CJ ONE's 3.5. U+one also leads on ads (none vs shown) and update cadence (fortnightly vs monthly). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

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

U+one holds the better App Store score, 4.1 against 3.5. Both are backed by a comparable volume of ratings — 37 and 158 respectively. Written reviews complicate that: 71% of CJ ONE's written reviews are positive against 70% of U+one's, so the app with the better star average is not the one people write more warmly about.

CJ ONE ships an update monthly, U+one fortnightly. The most recent releases landed on September 25, 2026 and September 22, 2026 respectively.
