# Todo Math vs Math Gremlin

The clearest difference is rating: Todo Math at 4.7 against Math Gremlin's 3.8. Todo Math also leads on ads (none vs shown) and ratings volume (1.1K vs 4). Math Gremlin's advantage is review sentiment (100% vs 74%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Todo Math sells 6 one-off in-app purchases and Math Gremlin sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Todo Math holds the better App Store score, 4.7 against 3.8. That said, the two scores are not equally well evidenced: Todo Math has 1.1K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 74% of Todo Math'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.

Todo Math ships an update every 3 weeks, Math Gremlin every 2 months. The most recent releases landed on October 17, 2026 and October 14, 2026 respectively.
