# Mad Math vs Calcul Mental in Space

The clearest difference is rating: Calcul Mental in Space at 4.4 against Mad Math's 3.5. Calcul Mental in Space also leads on update cadence (every 6 days vs every 2 months) and ratings volume (576 vs 14). Mad Math's advantage is ads (none vs shown) and review sentiment (91% vs 79%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Mad Math sells 5 one-off in-app purchases and Calcul Mental in Space sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Calcul Mental in Space holds the better App Store score, 4.4 against 3.5. That said, the two scores are not equally well evidenced: Calcul Mental in Space has 576 ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 91% of Mad Math's written reviews are positive against 79% of Calcul Mental in Space's, so the app with the better star average is not the one people write more warmly about.

Mad Math ships an update every 2 months, Calcul Mental in Space every 6 days. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
