Verdict
The clearest difference is ads: YZ at none against Codibook's shown. YZ also leads on monetization model (free vs free with in-app purchases) and rating (4.9 vs 4.7). Codibook's advantage is review sentiment (81% vs 48%) and ratings volume (1.8K vs 29). On price, update cadence, in-app purchases and device support 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. Neither carries in-app purchases, so what you see is what you pay.
YZ holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Codibook has 1.8K ratings behind it against 29, so its average is the more settled of the two. Written reviews complicate that: 81% of Codibook's written reviews are positive against 48% of YZ's, so the app with the better star average is not the one people write more warmly about.
Codibook ships an update every 5 weeks, YZ every 2 months. The most recent releases landed on September 22, 2026 and September 27, 2026 respectively.
