ReceptionRating · Positive reviews · Number of ratings

Math Ninja AR holds the better App Store score, 4.5 against 3.6. That said, the two scores are not equally well evidenced: Math Ninja AR has 299 ratings behind it against 18, so its average is the more settled of the two. Written reviews complicate that: 76% of Code Kingdom's written reviews are positive against 28% of Math Ninja AR's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Code Kingdom ships an update every 3 months, Math Ninja AR every 3 weeks. The most recent releases landed on September 23, 2026 and October 10, 2026 respectively.
