# iCalc Triangle Calculator Pro vs Matrix Solver Step by Step

The clearest difference is rating: Matrix Solver Step by Step at 4.8 against iCalc Triangle Calculator Pro's 3.6. Matrix Solver Step by Step also leads on monetization model (free vs paid) and update cadence (weekly vs every 19 months). iCalc Triangle Calculator Pro's advantage is review sentiment (100% vs 80%). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Matrix Solver Step by Step holds the better App Store score, 4.8 against 3.6. That said, the two scores are not equally well evidenced: Matrix Solver Step by Step has 62 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 100% of iCalc Triangle Calculator Pro's written reviews are positive against 80% of Matrix Solver Step by Step's, so the app with the better star average is not the one people write more warmly about.

iCalc Triangle Calculator Pro ships an update every 19 months, Matrix Solver Step by Step weekly. The most recent releases landed on August 13, 2026 and September 25, 2026 respectively.
