Graphing Calculator is a tool for visualizing math. It can do arithmetic, algebra, and calculus, and graph equations in two and three dimensions. Graph explicit functions, implicit relations, parametric curves and surfaces, inequalities, points, vectors, contour plots, density plots, color maps, vector fields, ordinary differential equations, surfaces of revolution, coordinate transformations, conformal maps and complex-valued curves, surfaces, and ODEs. Use rectangular, polar, cylindrical, or spherical coordinates. Solve equations numerically, graphically, or symbolically.
"Graphing Calculator is one of the best examples of elegant power and clean user interface of any application I've seen." - Bruce Horn, creator of the Macintosh Finder.
Ratings and Reviews
Coolest math program ever!
This app is a port from a program that shipped with the Mac back in the PowerPC days. It was the coolest math program ever back then, and it still is. It is great to have it available on iOS. It is worth many times the price.
This app helps math students at all levels visualize functions and graphs in very enlightening ways. We use it frequently in many math classes at the college where I teach. It's capabilities cover every level of math from beginning algebra to multidimensional calculus, complex numbers, and four dimensions, and everything in between. I wish this app had been available when I was a student. The user interface is a model of simple, elegant, and friendly design. It is also beautiful and fun.
There are lots of math graphing apps now, but none is both as powerful and easy to use as this one.
Still the best graphing calculator out there!
Of all the graphing calculators I have used, Pacific Tech's Graphing Calculator is the best because, unlike the others, the user interface does not get in the way of actually doing the math. By comparison, other apps have clumsy user interfaces that get in the way — resulting in frustration, wasted time, and distracting away from the mathematics of interest. Whereas this app's user interface gets out of your way, so you can focus on the math without having to battle the program! Thank you for bringing this to the iOS!
Awesome graphing calculator!
Awesome graphing calculator app! Version 1.3 exists on my old PowerPC macs running OS9 and I used it a lot for math / CS classes on my iBook G3 (I miss that machine). Glad it's now been updated and better than ever. The developer was quick to reply about my inquiry. Highly recommended!
P.S. Since upgrading to iOS 11, I noticed that the app keeps crashing now, especially if I try to rotate or zoom in on 3D graphs. Any plans on fixing the bug? I really like this app. Hope it gets fixed.
With Family Sharing set up, up to six family members can use this app.
