# Math Master vs Mathmaji

The clearest difference is review sentiment: Mathmaji at 100% against Math Master's 45%. Mathmaji also leads on update cadence (weekly vs every 5 weeks) and iOS requirement (14.0 vs 17.6). Math Master's advantage is ratings volume (321 vs 8) and rating (4.2 vs 4.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Math Master sells 5 in-app purchases, starting at $1.99 per 7 days and Mathmaji sells 2 in-app purchases, starting at $15.00 per month. Whichever you choose, the download price is not the number that matters.

Math Master holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Math Master has 321 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 45% of Math Master's written reviews are positive against 100% of Mathmaji's, so the app with the better star average is not the one people write more warmly about.

Math Master ships an update every 5 weeks, Mathmaji weekly. The most recent releases landed on October 10, 2026 and October 12, 2026 respectively.
