Verdict
The clearest difference is rating: O at 4.5 against Code Editor's 3.2. O also leads on ratings volume (8.6K vs 43) and update cadence (every 2 weeks vs every 5 weeks). On price, ads, in-app purchases and monetization model 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. Code Editor sells 1 one-off in-app purchase and O sells 23 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
O holds the better App Store score, 4.5 against 3.2. That said, the two scores are not equally well evidenced: O has 8.6K ratings behind it against 43, so its average is the more settled of the two. Written reviews point the same way: 54% of Code Editor's written reviews are positive against 63% of O's.
Code Editor ships an update every 5 weeks, O every 2 weeks. The most recent releases landed on October 13, 2026 and October 14, 2026 respectively.
