TI-Nspire™ CAS

Let’s be honest: I have a calculator on my iPad to do homework on my iPad. To do this, I need two windows so that I can both see my work and do the calculations. You can’t do that with this app.<br/><br/>Sure, you can overlay another app on top of it, but when you do that, the in-app keyboard crashes, making the app totally useless.<br/><br/>It’s a great calculator, but without the ability to have two windows, it’s pretty useless.<br/><br/>I requested a refund from apple, but they won’t grant it.

Don’t download this app if you are a teacher b/c it cannot fill that role. Otherwise it works fine as an over-priced calculator.

Wish they will add an emulator just like the desktop version

The greatest calculator on the market.

Can’t integrate Gaussian distributions which is needed in physics.

Unfortunately, the app is way less stable than I expected as it crashed multiple times on my iPAD pro, while doing different things. Also, it's not intuitive: I don't have an easy way to discover the name of the functions for the things I'd like to do. I'm sure that if I insist on using it for some time could get better, but the fact that crashes it's very demotivating. I've used way cheaper symbolic calculators on iOS that turned out to be much more stable. I expected much more from TI.

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.
