# Quick Graph vs Photomath

The clearest difference is review sentiment: Quick Graph at 94% against Photomath's 51%. Quick Graph also leads on iOS requirement (9.0 vs 14.0). Photomath's advantage is ratings volume (733K vs 405) and update cadence (monthly 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 Photomath sells 9 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

Photomath holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Photomath has 733K ratings behind it against 405, so its average is the more settled of the two. Written reviews complicate that: 94% of Quick Graph's written reviews are positive against 51% of Photomath's, so the app with the better star average is not the one people write more warmly about.

Quick Graph ships an update every 3 months, Photomath monthly. Both last shipped on September 25, 2026.
