# Todo Math vs 数感星球

The clearest difference is review sentiment: 数感星球 at 96% against Todo Math's 74%. Todo Math's advantage is ratings volume (1.1K vs 71) and rating (4.7 vs 4.5). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Todo Math sells 6 one-off in-app purchases and 数感星球 sells 23 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 4.5. That said, the two scores are not equally well evidenced: Todo Math has 1.1K ratings behind it against 71, so its average is the more settled of the two. Written reviews complicate that: 74% of Todo Math's written reviews are positive against 96% of 数感星球'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, 数感星球 every 2 weeks. The most recent releases landed on September 24, 2026 and September 21, 2026 respectively.
