"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!

8 of 25Hands down awesome when I can’t get the Ti-nSPIRE CX CAS, and sometimes in place of the iNspire when the app is able to handle what I need!!!!
I've had this app on my phone for an eternity, and it just continues to work when I need it. No in-app purchases other than a one-time $1.99 purchase (I forgot at first I'd made this purchase, but it's honestly less than most stuff costs these days). No data collection. No one trying to advertise to you in the app. It just works. Not all heroes wear capes, but this app developer is a hero.
I can’t even graph complex functions? Euler’s formula is a beautiful thing and really quite simple, yet I cannot graph that on this app. One of the greatest advantages of 3d graphing is the ability to see complex functions, and this app does not take advantage of that at all. Very disappointing, if this is what their paid app is like I am not interested.
Quick Graph has a beautiful display and quick and straightforward equations entry. The display axes are configurable for scale, and the entire display can be translated easily with your thumb, allowing you to observe the behavior of the function over different ranges of abscissa and ordinates. High quality.
I recently completed my M.S. in Mathematics and QuickGraph was a great help in most of my courses work. At least the parts that weren’t theoretical. It was well worth paying for the upgrade.
Great app! What’s even greater is that the developers are still updating it a decade after its initial launch. This could be the longest lasting app on my phone.
The app is much quicker than graphing on a TI 84 or a TI 89. One can change the size of the graph effortlessly and choose the color for each of the graphs. One can graph algebra equations, trigonometric, exponential and logarithmic problems easily. I’m using the app frequently for pre-Calc and I highly recommend it. The iPad version is much larger and the graphs are more beautiful!
