# Math Zen vs Calculus

The clearest difference is rating: Calculus at 5.0 against Math Zen's 4.8. Math Zen's advantage is ratings volume (6 vs 1). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Math Zen sells 6 in-app purchases, starting at $3.99 per 7 days and Calculus sells 4 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Calculus holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Math Zen has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Math Zen ships an update every 2 days, Calculus every 3 days. The most recent releases landed on October 26, 2026 and October 25, 2026 respectively.
