I searched for this for quite some time as well. I tried to download files that could be put into an emulator so I could run this calculator on my computer. I saw this on Youtube so I wasn't too sure.

But I finally found an emulator software that allows running this calculator on your computer for a trial period of 90 days (You could buy a paid version as well).

Go to this link and download the software for whichever operating system you use, then you could select the trial version once it downloads.

That's it!

I hope this was helpful. Good luck with your AP exams!

Thanks for this information. Unfortunately, this appears to only be available for computers (desktop/laptop). I have periodically searched the Apple Store for my iPad and the Google Play Store for my Android smartphone to see if TI has entered these markets to make official calculators for these platforms. I do get "hits" on the various TI model numbers I enter, but they are for third party apps that specify things like, "works similar to TI 84." I really want a genuine TI product, and I've wondered why they haven't gotten into what should be a lucrative market for them.

I'm guessing that the reason is that most people want free apps or ones that don't cost very much (under $10), and this one would likely cost more than what most mobile users are willing to pay for it. This is true for me for most apps, but a TI simulator app is one I'd spend a little bit more on. The other possible reason is that it would take up too many resources - storage space, processing time, battery life, etc. - to make it viable for a mobile platform.

I didn't see anything on this page or in your post on how much it costs after the 90-day trial period. Although I said above that I would not mind paying for such an app, but an amount such as, say, $399.95, would be way too much. I may try getting it for my Windows computer and see how much it would eventually cost. And I only want to buy something, not license it like Microsoft is moving people towards for their Office products or pay periodically such as monthly like some of the calculator apps do for turning off ads or getting extra feature. I want to pay once and then be done paying for it.
