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.

- 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.

- 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 in CSV format and process it!
- 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 ( to get you going. And you can always contact our support ( for help!
- Offline computation: PocketCAS doesn't need an internet connection to calculate results.

"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!"

What’s New

Version 3.14

New Feature: Added support for dark mode on upcoming versions of iOS.
New Feature (BETA): Added extremely rudimentary support for showing calculation steps for a few functions. Enable "Calculation Steps" in the document settings, then e.g. calculate "diff(sin(x)^3)" to see an example. Note that calculation steps will need to be enabled independently for each document, and the usefulness of the steps can vary greatly. We can not guarantee that the quality of these steps will ever increase, so this feature might remain "Beta" forever.
New Feature: You can now set a custom legend label for a graph, e.g. "Parabola" instead of "x^2".
Improvement: Increased the size of the matrix editor on iPad.
Improvement: Updated to the latest version of the CAS kernel.
Improvement: Internal rearchitecting and modernizing of the app.
Note: PocketCAS now requires iOS 11 or newer.

Excellent math app

Amazing. It finds the answer to the integral ∫(1/(x^3-1),x,0,∞). Wolfram could not do that. One thing I really like about this app is how it allows you to create documents (consisting of calculation steps, plot steps, or script steps) which can be saved, imported, or exported. In any step in a document the variable Ans always contains the result of the last calculation so, for example, you can have pocketcas differentiate a function in x in a calculation step, and follow with a plot step that plots Ans, to see the graph of the derivative. Also any step can be duplicated, which saves a lot of typing when you want to do similar things. On graphs of functions, you can easily zoom in and out, display x and y coordinates while moving along a curve, and see a table of coordinate points that belong to the curve. It works very well with complex numbers and symbolic calculations. It is easiest to use on an iPad, but I've had no problem using it on my iPhone.

I have used mathematical modeling throughout my career to forecast manufacturing throughput. This application is so much more versatile to the developing of models than a spreadsheet, because it allows you to compare different components of the model in the same graph and make hypothetical changes by simply using math.

The iPad version takes this application to a new level. I can now carry a mathematical laboratory with me to the field to make changes or adjustments which will synchronize with the cloud so that I can continue my work in my Mac.

Excelente app

Delivers what it promises. I'm reviewing calculus and it has proven to be a great help; I wish I had it when in college!

It might not be as powerful as some of the math programs for the Mac or PC (I have wxMaxima on my Mac), but it's ease of use and portability (iPhone) makes it a good choice. It also helps that it is document oriented; you work, say, the exercises of a chapter you are studying and when done just save it under a meaningful name.
