PocketCAS is the most advanced mathematics application for iPhone and iPad. It can help you with any kind of math problem, from elementary school all the way up to calculus, algebra and statistics. It can replace your old graphing calculator, help you with your homework, and assist you in any kind of calculation for university or work. This app is an indispensable tool for every student, teacher and engineer. It makes college-level calculus and algebra easy and can help you in a wide range of cases. It provides features comparable with a TI-89 calculator and combines them with a modern, intuitive interface and incredible graphics capabilities. MATHEMATICAL CAPABILITIES - 2D Plots: Quickly create 2D cartesian, implicit, polar or parametric plots. - 3D Plots: PocketCAS draws stunning 3D plots! Supports x-y cartesian plots, parametric area plots and parametric line plots. - Animated plots: Use the variable 'anim' to animate any plot over time. - Calculus: Calculate limits, derivatives, integrals and taylor expansions. - Linear Algebra: Invert and multiply matrices or calculate determinants, eigenvalues and much more! - Algebra: Perform integer and polynomial factorization and division, use permutations, and more. - Solving: PocketCAS will solve almost any equation for you. It even supports systems of linear equations and ordinary differential equations! - Scripting: PocketCAS' C-style scripting language allows you to define custom functions, use conditional expressions, loops and also supports recursion. - Physical Units: Constants and units are provided out of the box. Simply enter physical formulas with the corresponding units and convert results to the units you prefer. ADDITIONAL FUNCTIONALITY - iCloud support: Sync documents between your Mac, iPhone and iPad! - Export: Print or export plots, entries or the whole document as PDF! - Document Import: Load functions and variables from existing documents to re-use your work in other calculations. - CSV Import: Load tabular data and process it in CSV format! - Mathematical keyboard: PocketCAS' mathematical keyboard is unmatched on the App Store. - Help: All functions are explained in the built-in reference. If you're stuck, there's plenty of tutorials as well as a manual (https://pocketcas.com/manual) to get you going. And you can always contact our support (https://pocketcas.com/support) for help! - Offline computation: PocketCAS doesn't need an internet connection to calculate results. USER REVIEWS "This program has an incredible amount of power for such a compact program. I teach high school math, and this program can work with all sorts of expressions, graphs, and help check my work. Definitely worth it!" "You will love this calculator. It's powerful to calculate everything, doesn't matter you're a high school student or college student. Specially for the people who like to solve problems with graphs!" "This app is so powerful and slick looking. It is totally amazing and what it can do." "One of three Apps I use when teaching A Level maths. Have recommended to numerous students. Excellent." "This is one of the best. The CAS capabilities are compatible to only two other apps, and this one is all offline and includes countless additional features. It's never steered me wrong and is the first thing I go to when I'm in a hurry to figure something out. If you're a student this is pretty much as good as it can get." "I am 8 years old and this App is awesome! It helps you learn calculus quickly. It's a work of art!"



  • Superb!

    They just keep improving it!
  • Best calc for math programming

    By S9mcderm
    I love PocketCAS, I use it at work to quickly solve various math programming problems. It stores variables and outputs files so I can save them for later. Simple to use, yet powerful enough to handle my most complex calculus problems. Buy the pro version, it’s worth the $10.
  • PocketCAS?

    By glider_driver
    Find yourself something more intuitive and in line with typical calculator functions. I don’t like the “New entry” line. I like to have all calculation that I performed moment ago on the screen. As an engineer I am using TI 89 Titanium, but I downloaded this calculator for situations where my TI is not handy. I am rather disappointed.
  • Excellent!

    By _IYQ2_
    This is an excellent app that I use all the time. I keep it handy on my front page.
  • Greatest calculator ever

    By TheRaven1
    I am really impressed with the incredible power in this app it is my go to for all my calculations. And worth every penny for anyone who needs a calculator that can quickly power through advanced math.
  • Amazing App

    By HybridMouse
    I was looking for a calculator app that also had easy 3d graphing capabilities and was not disappointed! I had one problem with the graphs but I contacted the devs and they were super awesome as they patched the bug within like 1-2 weeks. Great app if you need a powerful cas calculator and 3d grapher!
  • Best math app

    By AndyLee73
    The profound utility of this app is hard to describe. And the brilliant execution should be a model for other apps. This is one of the best apps I own.
  • Well Worth The Purchase

    By NumberphileFan
    Disclaimer: I’m not particularly well versed in either higher math or calculators; these are just my amateur opinions. This app is amazing in its ability to perform mathematical operations—notably 3D graphing. Because of its being an app, it taps into your smartphone’s processor and touchscreen, making it a much more user-friendly alternative to, say, what the TI-Nspire tries to accomplish. (I don’t actually own the TI-Nspire, by the way; I’m merely relating to a video I saw on YouTube by VBlogMag that does a fairly good job reviewing various calculators.) what I mean by that is that when panning and zooming on a graph—either 2D or 3D—there is zero lag, and I really do mean that I experience no noticeable lag (obviously there is some lag, due to the limitations of computer processors, but that’s beside the point.) In fact, I’d say that the dedicated calculator with the closest comparable performance that I have seen would be the HP Prime Graphing Calculator (again, I don’t actually own it, I just saw the review by VBlogMag.) But now we’re comparing an app that costs a couple of dollars to calculators that range from $120-$140. Undoubtedly there are advantages to owning the dedicated calculator. For example, actual keys are nice to have, and I’m sure there are some more in-depth functions with possibly a slightly more streamlined operation, but this app is quite close, to the point that I would argue that it’s down to personal preference about how one likes their calculator’s operating system to work. As an additional bonus, I have never, to this date, experienced any bugs myself, although it seems that other people do. On the upside, the developers offer updates, bug fixes and performance improvements frequently enough to be helpful and encouraging that if you do find a bug, they’ll be right on it. In a nutshell, I would seriously recommend trying this app out to see if it could work as a potential alternative to an ~$130 dedicated calculator. (One could use this smartphone app in almost all scenarios in which one could use a HP Prime Graphing Calculator or a TI-Nspire, because rarely are those dedicated calculators allowed in tests.)
  • Great CAS app

    By BeakerBrn
    Powerful, versatile, and easy to use. Thank you! Love the updates and expanding capabilities.
  • Great App - Excellent tool for finance calculus

    By koomanchu
    This tool is a lifesaver for checking complex economics and finance theorems. I read lots of academic research reports that require calculus and it's a breeze with PocketCAS to check the textbook algorithms and then convert them into real workable and understandable code. Super product!
