# Pi Digits Memory Game vs Math 24

The clearest difference is rating: Math 24 at 4.7 against Pi Digits Memory Game's 4.2. Math 24 also leads on update cadence (every 6 weeks vs every 9 months) and ratings volume (2.1K vs 58). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Pi Digits Memory Game sells 1 one-off in-app purchase and Math 24 sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Math 24 holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Math 24 has 2.1K ratings behind it against 58, so its average is the more settled of the two. Written reviews complicate that: 82% of Pi Digits Memory Game's written reviews are positive against 76% of Math 24's, so the app with the better star average is not the one people write more warmly about.

Pi Digits Memory Game ships an update every 9 months, Math 24 every 6 weeks. The most recent releases landed on October 16, 2026 and October 19, 2026 respectively.
