Quick Graph app for iPhone and iPad
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.
Its 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!

Pros and cons of Quick Graph app for iPhone and iPad
Quick Graph app good for
This application deserves a very good mention. It is perfect way to visualize any function in 2D or 3D with strightforward writing, go "inside" the graph and play with it at your will. A powerful tool to play with maths and having fun while learning.
I use it every time I run into complicated formulas in physics to "sniff" at where the behavior consistently goes. That greatly helps to test the coherence beneath the maths.
I regret not to have had such a too, in my early days as a student, I d certainly saved a bunch of time...
Easy, useful, convenient, efficient.
5 star App, no doubt.
Use it for my students and myself
This app really helps, but when you upgrade to iOS7, it does not work well.
Manufacturer, please, fix it.
This program is fantástic. I have liked s o much since I knew.
It is a good soft, without any doubt!
It is being impossible to edit an equation; the keyboard covers the editable equation expression.
I have used to assist students, specially for solve doubts in math, of course. Really a good tool for teachers.
Some bad moments
Im trying to do math and Im using this graph app and it is sooo horrible
Its not working properly, even regular easy graphs work! Dont use this
I can only draw simple graphs like y=x and if you want to draw "Log" graphs you have to pay additional 3 $
Very easy to use. Fast and accurate. I tell all my students about it and to buy it.
When i work in R^3 the app crashes and i get dots instead of the surface.
In any text field, I expect that I can press and hold over a certain point of text and a magnifying glass will appear so I can specify where to move the cursor. I cant do that in this app so editing formulas is difficult. Deleted it immediately.
Was amazing until they released the newest version which doesnt support implicit functions unless you upgrade. Immediately uninstalled.
