King of Math holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: King of Math has 3.1K ratings behind it against 21, so its average is the more settled of the two. Written reviews complicate that: 90% of King of Math's written reviews are positive against 100% of Mental Math Master's, so the app with the better star average is not the one people write more warmly about.
King of Math ships an update every 3 weeks, Mental Math Master weekly. The most recent releases landed on October 30, 2026 and October 24, 2026 respectively.
