# OCO vs ZBM

The clearest difference is rating: OCO at 4.6 against ZBM's 3.7. OCO also leads on monetization model (free with in-app purchases vs subscription) and ratings volume (2.4K vs 3). ZBM's advantage is ads (none vs shown) and update cadence (fortnightly vs every 5 weeks). On price, in-app purchases and device support there is nothing between them.

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

OCO holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: OCO has 2.4K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 73% of OCO's written reviews are positive against 62% of ZBM's.

OCO ships an update every 5 weeks, ZBM fortnightly. The most recent releases landed on October 13, 2026 and October 10, 2026 respectively.
