# Quadratic Master vs Linear Equations Calculator

The clearest difference is rating: Quadratic Master at 4.6 against Linear Equations Calculator's 4.1. Quadratic Master also leads on ratings volume (333 vs 28). Linear Equations Calculator's advantage is update cadence (every 3 weeks vs every 5 months) and device support (3 vs 1). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Quadratic Master sells 1 one-off in-app purchase and Linear Equations Calculator 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 4.1. That said, the two scores are not equally well evidenced: Quadratic Master has 333 ratings behind it against 28, so its average is the more settled of the two. Written reviews complicate that: 74% of Quadratic Master's written reviews are positive against 75% of Linear Equations Calculator's, so the app with the better star average is not the one people write more warmly about.

Quadratic Master ships an update every 5 months, Linear Equations Calculator every 3 weeks. The most recent releases landed on September 20, 2026 and September 14, 2026 respectively.
