TI-Nspire™ CAS

Good app to get if you want to use your ti-nspire abilities on the iPad. $30 is a steal considering the real thing is $150. Make sure to get this one (CAS version) because the cost is the same as the non CAS. You’re probably not going to bring an iPad to an exam, so the CAS version is nice to have.

It would have been nice if the user interface was the same as the actual calculator, but for some bizarre reason, the developer chose to make something that bears absolutely no resemblance to the TI Nspire, or any other calculator for that matter. It pretty much uses a glorified iPad popup keyboard as the main input, which, to put it mildly, is very clumsy. Since part of the purpose of this app is to be able to use and learn the calculator when you don’t have it with you, it makes no sense to have designed the app the way they did. What is really odd, is that the in PC version of this app the interface is almost exactly the same as the Nspire, so why they didn’t do that here is beyond me. Despite all that, It’s a powerful calculator and it’s great having a CAS on the iPad. Overall, it is a great tool despite the frustratingly awkward way you have to work with it.

I use this app to support my tutoring students that have nSpire CX calculators. Sometimes they have trouble learning to zoom on their calculator & the iPad's pinch & drag mode makes resizing graphs much easier. Once they get it where they like how it looks, I have them copy the x-y settings so they learn more about their calculator. I just wish this had some more of the teacher features like the press-to-test mode so I didn't have to break out my real calculator to get them used to preparing for exams.
