Free Graphing Calculator app review: the most advanced mathematics application for iPhone and iPad

Introduction

This is an incredibly powerful calculator app for iPhone and iPad that offers features for performing all kinds of functions from elementary all the way up to calculus, providing you with a one-stop tool for all your mathematical needs.

The best iPad apps for calculators

I’ve reviewed a handful of calculator apps over the past year or so, and the majority of them tend to simply be glorified versions of the basic iOS Calculator widget with little more than a spruced-up interface and perhaps a couple of additional functions.

The developer of this app, on the other hand, has certainly pulled out all the stops, providing a ton of functions that, to be quite honest, go way over my head! From what I’ve seen so far, this is a very solid development, and it receives a very strong recommendation from me.

Perform All Manner of Algebraic Functions

Besides the basic functions of addition, subtraction, multiplication, and so on, Free Graphing Calculator - PocketCAS lite (Calculus, Algebra and more!) allows you to draw both 2D and 3D plots, including Cartesian, implicit, polar, and parametric.

You can also perform linear algebraic equations, including functions for the inversion and multiplication of matrices. You can also calculate eigenvalues, determinants, and many more esoteric terms that are completely lost on an innumerate writer like myself!

 

Supports a Powerful C-Style Scripting Language

There is a powerful C-style scripting language supported in Free Graphing Calculator that you can use for conditional expressions, recursion, and various other custom functions that you can define as required.

In addition to these and many other great functions, this app also enables you to export your plots and entries in PDF file format, and you can even use iCloud to synchronize the app between your devices, making it a cinch to move your documents from your iPhone to your iPad, and back again.

The developer claims that the mathematical keyboard in this app is the most powerful in the entire App Store, and from what I’ve seen of comparable apps within the Utilities category, I would tend to agree with that statement
