# Quick Graph vs Linear Equations Calculator

The clearest difference is rating: Quick Graph at 4.6 against Linear Equations Calculator's 4.1. Quick Graph also leads on review sentiment (94% vs 75%) and ratings volume (405 vs 28). Linear Equations Calculator's advantage is update cadence (every 3 weeks vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Quick Graph 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.

Quick Graph holds the better App Store score, 4.6 against 4.1. That said, the two scores are not equally well evidenced: Quick Graph has 405 ratings behind it against 28, so its average is the more settled of the two. Written reviews point the same way: 94% of Quick Graph's written reviews are positive against 75% of Linear Equations Calculator's.

Quick Graph ships an update every 3 months, Linear Equations Calculator every 3 weeks. The most recent releases landed on October 12, 2026 and October 2, 2026 respectively.
