# King of Math vs Mental Math Master

The clearest difference is in-app purchases: Mental Math Master at none against King of Math's 1. Mental Math Master also leads on update cadence (weekly vs every 3 weeks) and review sentiment (100% vs 90%). King of Math's advantage is ratings volume (3.1K vs 21). On price, rating, ads and device support there is nothing between them.

Both are free to download. King of Math sells 1 one-off in-app purchase. Mental Math Master asks for nothing beyond the download.

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 November 1, 2026 and October 24, 2026 respectively.
