# CU vs OOKBEE

The clearest difference is rating: OOKBEE at 4.7 against CU's 2.8. OOKBEE also leads on ratings volume (249 vs 4) and update cadence (every 2 months vs every 6 months). CU's advantage is review sentiment (93% vs 81%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. CU sells 17 one-off in-app purchases and OOKBEE sells 20 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

OOKBEE holds the better App Store score, 4.7 against 2.8. That said, the two scores are not equally well evidenced: OOKBEE has 249 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 93% of CU's written reviews are positive against 81% of OOKBEE's, so the app with the better star average is not the one people write more warmly about.

CU ships an update every 6 months, OOKBEE every 2 months. The most recent releases landed on September 16, 2026 and September 21, 2026 respectively.
