TI-Nspire™ CAS

By Texas Instruments

Open iTunes to buy and download apps.


Texas Instruments, the No. 1 recommended brand of graphing calculators in the U.S., has optimized its most powerful Computer Algebra System (CAS) math engine for an all-in-one iPad app that makes teaching and learning math more engaging, meaningful and … fun!


Open the door to math mastery with the first-in-class iPad CAS app that delivers comprehensive graphing, data entry and analysis, statistical modeling and calculating functionality.

Solve equations with algebraic precision, factor and expand variable expressions, complete the square, find antiderivatives, compute limits, find exact solutions in irrational form and more.

Make math more meaningful by importing images from the iPad camera or photo library and overlaying graphs and equations on them to illustrate abstract math principles in the real world.*

Visualize crucial connections by observing how equations change — in real time, on one screen — when you touch, grab and interact with shapes, graphs and objects on the screen.

Graph functions, inequalities, implicit functions, conic sections, scatter plots, statistical plots and regression models, 3D graphs, parametric, polar and differential equations.

Enter equations in proper math notation so math symbols and formulas on the screen are identical to those in text books and on the board.

Deepen understanding by exploring hundreds of free activities for Pre-Algebra, Algebra, Geometry, Calculus, Statistics, Pre-Calculus and more from the online Math Nspired resource center.

Create and store work on your iPad, and share it using your Email or Dropbox account.

Customer Reviews

Great app, split screen?

Great app. Does all you would want it to do and functions well. If you like TI calculators you will love this app. If you have used an Nspire handheld it will be very easy to use. As a math teacher I use it to help students learn concepts and show the steps they can take on their handheld.

Now that the iPad offer split screen multi tasking this app really needs to take advantage others feature. It is common when working on your iPad to want to see the problem you are working out as well as see the calculator. Please make it so it can go split screen soon!

Very stable app

I use the app constantly. In my classroom my students are used to the TI nspire and it is very convenient to have one handy. The app works flawlessly this time.


This app is just great. It is best in my opinion to buy this over TI nSpire because I use this and the TI nSpire CX physical calculator. Work great together and if you need a standardized calculator like for the ACT it is useful to just have the nSpire CX.
