# Calculoo vs Math Master

The clearest difference is review sentiment: Math Master at 45% against Calculoo's 0%. Math Master also leads on update cadence (every 5 weeks vs every 17 months) and ratings volume (321 vs 1). Calculoo's advantage is rating (5.0 vs 4.2) and in-app purchases (none vs 5). On price, ads and device support there is nothing between them.

Both are free to download. Math Master sells 5 in-app purchases, starting at $1.99 per 7 days. Calculoo asks for nothing beyond the download.

Calculoo holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Math Master has 321 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of Calculoo's written reviews are positive against 45% of Math Master's, so the app with the better star average is not the one people write more warmly about.

Calculoo ships an update every 17 months, Math Master every 5 weeks. The most recent releases landed on September 9, 2026 and October 1, 2026 respectively.
