# Parametric Factorization vs Derivative Calculator App

The clearest difference is rating: Derivative Calculator App at 5.0 against Parametric Factorization's 2.9. Derivative Calculator App also leads on monetization model (free vs free with in-app purchases) and iOS requirement (12.0 vs 15.0). Parametric Factorization's advantage is review sentiment (40% vs 0%) and ratings volume (8 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

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

Derivative Calculator App holds the better App Store score, 5.0 against 2.9. That said, the two scores are not equally well evidenced: Parametric Factorization has 8 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 40% of Parametric Factorization's written reviews are positive against 0% of Derivative Calculator App's, so the app with the better star average is not the one people write more warmly about.

Parametric Factorization ships an update fortnightly, Derivative Calculator App every 2 weeks. The most recent releases landed on August 26, 2026 and June 4, 2026 respectively.
