It is a powerful, high-quality graphing calculator that takes full advantage of the multitouch display and the powerful graphing capabilities of the iPad and iPhone, both in 2D and 3D. "The app you need to survive the next semester." -- Gizmodo A simple yet intuitive interface makes it easy to enter and/or edit equations and visualize them in mathematical notation. It's capable of displaying explicit and implicit (opt) equations as well as inequalities (opt) in both 2D and 3D, in all standard coordinate systems: cartesian, polar, spherical, and cylindrical, all with fantastic speed and beautiful results, which can be copied, emailed or saved to the photo library. It also includes an evaluation feature to evaluate equations at specific points and a library where you can store commonly used equations. Up to 6 equations can be visualized simultaneously in both 2D and 3D modes; this limitation can be removed by purchasing the advanced feature set. Features: - Enhanced 2D - 3D plotting mode for great hi-res graphics. - Adaptive 2D algorithms. - Hyperbolic and Inverse functions. - Functions such as Min, Max, if. - Configurable axis decimal / π - Independent 2D zoom - Support for cartesian, polar, cylindrical, and spherical coordinate systems. - Interactive expression evaluation. - Library for commonly used equations. - Swipe to delete equations from the equation list. - Save to photo library. - Copy to clipboard. - Turn graphs on/off - Drag to rotate - move. The advanced feature set gives you access to: - External screen support - 2D tracing. - 2D and 3D implicit graphs. - 2D and 3D inequalities. - Roots and Intersections (2D) - Value Table - More features to come!

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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. The most recent releases landed on September 17, 2026 and September 24, 2026 respectively.
