# Mental Math Trainer vs Sumaze!

The clearest difference is rating: Mental Math Trainer at 4.5 against Sumaze!'s 4.0. Mental Math Trainer also leads on ratings volume (228 vs 4) and update cadence (fortnightly vs every 2 months). Sumaze!'s advantage is in-app purchases (none vs 9) and review sentiment (83% vs 58%). On price, ads and device support there is nothing between them.

Both are free to download. Mental Math Trainer sells 7 in-app purchases, starting at $2.99 per month. Sumaze! asks for nothing beyond the download.

Mental Math Trainer holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Mental Math Trainer has 228 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 58% of Mental Math Trainer's written reviews are positive against 83% of Sumaze!'s, so the app with the better star average is not the one people write more warmly about.

Mental Math Trainer ships an update fortnightly, Sumaze! every 2 months. The most recent releases landed on October 14, 2026 and September 28, 2026 respectively.
