# Quadratic Master vs Parametric Factorization

The clearest difference is rating: Quadratic Master at 4.6 against Parametric Factorization's 2.9. Quadratic Master also leads on review sentiment (74% vs 40%) and ratings volume (333 vs 8). Parametric Factorization's advantage is update cadence (fortnightly vs every 5 months) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Quadratic Master 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.

Quadratic Master holds the better App Store score, 4.6 against 2.9. That said, the two scores are not equally well evidenced: Quadratic Master has 333 ratings behind it against 8, so its average is the more settled of the two.

Quadratic Master ships an update every 5 months, Parametric Factorization fortnightly. The most recent releases landed on September 20, 2026 and August 26, 2026 respectively.
