A Most Excellent App I just started my dabbling, and to say it succinctly, this app/emulator is a mirror of TI's line of graphing calcs, and a very stable one at that. The one thing to add I can think of is the ability to install apps(and from what I saw it's already suggested). But until then, I'm going to play with the software and check out loading the apps into a ROM via the emulator/TI's dev tools on the PC, when I've got time. Two thumbs, an outstanding app! You'll never have to use your abacus again!
Best calculator ever I just realized that after over a year of using it, I still haven't given this app a five star rating! So here it is. I'm a physics major, still in school, and I use this app nearly every day, and I've got to say, out of all my most frequent apps, this is the app that's given me the least sass. Even stock Android apps crash more than this app. Thanks! (P.S. I prefer the titanium edition, it's a very good looking layout, and would definitely recommend using that one over the normal layout)
Incredibly Simple I have a TI-89 Titanium which i use all of the time, but generally when i need it in any actual applications, i never have it in my bag and am forced to resort to my phone calculator. Standard Calculators just never cut it for me. Yet with this app, while i still love physically owning a TI-89, guarantee's i'll never be without it even if the actual device isn't with me. Excellent App! This is truly using the capabilities of a smart phone!
Stoked. Great emulator I had been looking for a calculator app for android that could do the things my old ti-92 could do. Was very surprised there really was nothing with all that functionality. But this emulator does the trick. Why change of habits when you can put old software on new hardware! Thanks so much!!
I love it! Just like my 89 titanium. I love that the buttons are exactly like the actual calculator. Of course it is a little skewed, but it has to be to fit everything on the screen. I think it is great and I am very happy to have it. Great job! Ignore the people on here that don't know how to load a ROM (or follow simple directions). Also, if you have a Ti-89, you would know how to exit the app properly.
Very Good I used a 89 when in my calc class long ago. I do math as a hobby now, but didnt want to buy another calculator for the purposes of having some fun with math. So far i see the 89 run flawless, however i see some quirks with the 89 titanium rom. I tried the titanium first, but removed it and installed the 89 rom instead. Still i think its a great emulator. You can get the roms from ti website
