Quick Graph is a powerful, high-quality graphing calculator for iPhone and iPad, in 2D and 3D. "The app you need to survive the next semester." -- Gizmodo Type an equation and see it right away, written in math notation and drawn in a graph you can move, zoom and rotate with your fingers. Explicit and implicit equations and inequalities, in cartesian, polar, cylindrical and spherical coordinates, all fast and beautiful. What's inside: - 2D and 3D graphs with a clean, full-screen design. - 3D surfaces drawn with Metal: smooth shading, transparency, wireframe, and zoom that fills the screen. - Adaptive 2D drawing with exact roots and extrema and clean asymptotes. - Equation groups: show, hide and move several equations together, with a shared n. - Annotations with Apple Pencil or your finger on 2D graphs. - A math keyboard with functions, derivatives and more on each key. - Hyperbolic and inverse functions, min, max, if, derivatives. - Axes in decimals or multiples of π, and independent zoom on each 2D axis. - A library of example and saved equations, including groups. - Share as a link, image or text; copy and paste equations; drag them between windows. - Light or dark appearance, multiple windows on iPad, and support for iPhone Duo. Up to 6 equations can be shown at once in the free version. The Advanced Features, a single one-time purchase with no subscription, add: - More than 6 equations. - 2D and 3D implicit equations and inequalities. - The variable n with a slider, to animate your graphs. - 2D tracing with roots, extrema and intersections. - Value table. - External display support. - Decimal / π axes and polar range settings. No ads, no subscription. Please visit the website for more details.
Neuronify
Explore the behavior of neurons and neural networks by combining different cells and connections. This educational tool allows you to observe how changes in individual neurons impact larger network behaviors. Build and experiment with your own simulations or use pre-made examples.
- Combine neurons with different connections
- Observe behavioral changes in networks
- Drag neurons and measurement devices
- Explore pre-made simulations
- Create custom neural network models

Version 1.0 is finally released! Neuronify is an educational tool meant to create intuition for how neurons and neural networks behave. You can use it to combine neurons with different connections, just like the ones we have in our brain, and explore how changes on single cells lead to behavioral changes in important networks. To build and explore neural networks, you drag neurons and measurement devices onto the screen. In addition, the app comes with several ready-made simulations for inspiration. If you like Neuronify, please leave a review :)

Verdict
The clearest difference is in-app purchases: Neuronify at none against Quick Graph's 2. Neuronify also leads on update cadence (every 4 weeks vs every 5 months) and rating (4.9 vs 4.6). Quick Graph's advantage is ratings volume (423 vs 13). On price, review sentiment, ads and device support 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 2 one-off in-app purchases. Neuronify asks for nothing beyond the download.
Neuronify holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Quick Graph has 423 ratings behind it against 13, 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 100% of Neuronify's.
Quick Graph ships an update every 5 months, Neuronify every 4 weeks. The most recent releases landed on October 31, 2026 and November 1, 2026 respectively.
