# OCO vs DEEMO II

The clearest difference is ads: DEEMO II at none against OCO's shown. DEEMO II also leads on rating (4.8 vs 4.6). On price, review sentiment, ratings volume and update cadence there is nothing between them.

Both are free to download. OCO sells 8 one-off in-app purchases and DEEMO II sells 43 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

DEEMO II holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 2.4K and 3.7K respectively. Written reviews complicate that: 73% of OCO's written reviews are positive against 68% of DEEMO II's, so the app with the better star average is not the one people write more warmly about.

OCO ships an update every 5 weeks, DEEMO II every 2 months. The most recent releases landed on September 23, 2026 and September 22, 2026 respectively.
