# Mathematical Expressions vs Parametric Factorization

The clearest difference is rating: Mathematical Expressions at 4.4 against Parametric Factorization's 2.9. Mathematical Expressions also leads on review sentiment (50% vs 40%) and iOS requirement (7.0 vs 15.0). Parametric Factorization's advantage is update cadence (fortnightly vs every 2 months). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Mathematical Expressions sells 1 one-off in-app purchase and Parametric Factorization sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Mathematical Expressions holds the better App Store score, 4.4 against 2.9. Both are backed by a comparable volume of ratings — 7 and 8 respectively. Written reviews point the same way: 50% of Mathematical Expressions's written reviews are positive against 40% of Parametric Factorization's.

Mathematical Expressions ships an update every 2 months, Parametric Factorization fortnightly. The most recent releases landed on September 28, 2026 and October 2, 2026 respectively.
