# Mental Math Games vs Math Gremlin

The clearest difference is rating: Mental Math Games at 4.7 against Math Gremlin's 3.8. Mental Math Games also leads on ads (none vs shown) and update cadence (every 9 days vs every 2 months). Math Gremlin's advantage is device support (3 vs 1) and iOS requirement (15.6 vs 26.0). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Mental Math Games sells 7 in-app purchases, starting at $4.99 per month and Math Gremlin sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Mental Math Games holds the better App Store score, 4.7 against 3.8. That said, the two scores are not equally well evidenced: Mental Math Games has 1.2K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 93% of Mental Math Games's written reviews are positive against 100% of Math Gremlin's, so the app with the better star average is not the one people write more warmly about.

Mental Math Games ships an update every 9 days, Math Gremlin every 2 months. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
