Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
