# MathPapa vs iCalc Triangle Calculator Pro

The clearest difference is rating: MathPapa at 4.7 against iCalc Triangle Calculator Pro's 3.6. MathPapa also leads on update cadence (every 3 weeks vs every 19 months) and ratings volume (17K vs 5). iCalc Triangle Calculator Pro's advantage is in-app purchases (none vs 2) and review sentiment (100% vs 78%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. MathPapa sells 2 in-app purchases, starting at $9.99 per month. iCalc Triangle Calculator Pro asks for nothing beyond the download.

MathPapa holds the better App Store score, 4.7 against 3.6. That said, the two scores are not equally well evidenced: MathPapa has 17K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 78% of MathPapa's written reviews are positive against 100% of iCalc Triangle Calculator Pro's, so the app with the better star average is not the one people write more warmly about.

MathPapa ships an update every 3 weeks, iCalc Triangle Calculator Pro every 19 months. The most recent releases landed on November 9, 2026 and November 3, 2026 respectively.
