Verdict

The call

The clearest difference is review sentiment: Night Zookeeper at 83% against Code Ninjas's 39%. Night Zookeeper also leads on update cadence (every 2 months vs every 5 months). Code Ninjas's advantage is in-app purchases (none vs 12) and rating (4.8 vs 4.6). On price, ratings volume, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Code Ninjas holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 1.2K and 592 respectively. Written reviews complicate that: 39% of Code Ninjas's written reviews are positive against 83% of Night Zookeeper's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Code Ninjas ships an update every 5 months, Night Zookeeper every 2 months. The most recent releases landed on October 12, 2026 and October 11, 2026 respectively.
