Bare minimum emulator This app has so much potential, but I feel like it falls flat. Suggestions: we all know what it looks like, can we have an option for a button grid, rather than buttons with dead space around them? Also, make the text on the buttons (in grid form) change with the pressed function keys. Make the screen area slightly smaller for more room for buttons. That would make it perfect in my opinion.

Wow!! I can't believe I got this to work! For those who rate one star: go back to using a landline! You have no business with such an advanced device! **But with latest update the buttons aren't as responsive as they used to be but I do like the improvements especially since I upgraded to an HTC One! *2014 update: Now the keys are very responsive, I don't know how since there was no update but I'm love this app! My favorite one!
John Thomson
Fantastic port Love the new look on latest update with larger keys, etc. Works just like my physical calculator, very stable. Thanks so much for a wonderful tool!
Ian Boys
Fantastic Simply put, this is a superb emulator. It is great to always have the power of a Ti89 on hand.
Anupam Biswas
Works fine but having a bug This calculator is working awesome on my samsung galaxy win.But I ran into problems when I hit 2nd+on key.Instead of quitting the emulator application completely,the virtual screen just goes off and the virtual buttons become unresponsive....then I have to quit it using the home button...how to fix this?
James Hedin
sugestion as much as I love the ti89 interface, I always find myself trying to use some touch controls and such. is there any chance of adding some?

Oh My This app makes me want to go back in time. I would go to my 5th grade teacher and ask "why can't I use a calculator?" and when the robotic response came "You won't always have a calculator with you!" I would punch her in the face. I mean seriously, I saw this coming 32 years ago when I was 10. I LOVE this app because I loved my TI89! And it is ALWAYS with me...take that Ms. Chatterton!
I would love if... I actually own a TI  89 Titanium calculator but it is starting to break after 10 years of usage so I was hoping this could substitute it but I cannot install any new apps as it goes into the browsing section for me to point to the file it immediately force closes I have sent a bug report will definitely change to 5 stars when fixed. It also force closes when I enter the configuration menu
Options disappeared? Where did it go? On Nexus 4, the 3 dot menu is gone.

Listen Read Device Only Added Installed Get a TI82, TI83, TI83+, TI85, AND TI86 emulator for your phone!
Andie Graph is an Android port of the AlmostTI emulator by Marat Fayzullin  http://fms.komkon.org/
*** ROM not included. Why? http://dgmltn.com/roms ***
The TI8X series of calculators work great as standalone calculators, showing 8 lines of history, using standard mathematical notation. Each model was designed with more specific purposes in mind:
The TI82 is designed for algebra and trigonometry. Graph and compare functions, perform variable substitution, and solve single variable equations.
The TI83 is designed for statistics and trigonometry. Graph and compare functions, and perform data plotting and analysis.
The TI85 is great for engineering and computer science. Graph and compare functions, perform bit manipulation and convert between numeric bases.
The TI86 is great for engineering and calculus. Graph and compare functions, perform bit manipulation and convert between numeric bases. Solve differential equations, plot vector fields.
All models allow you to write programs in TIBASIC and perform basic scientific calculator operations.

Listen Read Device Only Added Installed AlmostTI turns your Android device into a Texas Instruments graphing calculator. It fully emulates TI84+, TI84+ Silver Edition, TI83+, TI83+ Silver Edition, TI73, TI83, TI85, TI86, TI82, and TI81 calculators made by Texas Instruments. And yes, if you have got a tablet, it will become a really BIG TI calculator. AlmostTI also lets you save your calculations at any point and then select from several previously saved tasks.
To run AlmostTI, you will need at least one calculator system ROM. AlmostTI does not include any calculator ROMs on its own, as they are intellectual property of Texas Instruments. You should place your own ROM, preferably dumped from the calculator you own, onto your internal storage. AlmostTI recognizes following ROM files (in upper or lower case):
TI85.ROM, TI86.ROM, TI81.ROM, TI82.ROM, TI73.ROM, TI83.ROM, TI83P.ROM, TI83SE.ROM, TI84P.ROM, TI84SE.ROM
TI85.ROM, TI86.ROM, TI81.ROM, TI82.ROM, TI73.ROM, TI83.ROM, TI83P.ROM, TI83SE.ROM, TI84P.ROM, TI84SE.ROM

The integration of functions is facilitated by selfcompletion of statements, also expressions of the interpreter is very flexible and allows the inclusion of any function: even the most complex are recognized and interpreted correctly.
The main functions recognized are: abs(x), acos(x), acosh(x), asin(x), asinh(x), atan(x), avg(x1,x2,...,xN), ceil(x), combin(x,y), cos(x), cosh(x), e(), exp(x), fact(x), floor(x), lg(x), ln(x), log(x,y), max(x1,x2,...,mN), min(x1,x2,...,xN), mod(x,y), pi(), pow(x,y), rand(), sign(x), sin(x), sinh(x), sqrt(x), sum(x1,x2,...,xN), tan(x), tanh(x), toDeg(x), toRad(x).
The graph allows an accurate view of the trend of function at any point in the plane. You can zoom and pan through the classical gestures.
There is also a tool which can calculate the value of the functions included, given the value of x (via a number or expression).

Graph 89  (with TI84 support)
Dritan Hashorva

Listen Read Device Only Added Installed Graph 89 is an emulator for the TI83, TI83 Plus, TI83 Plus Second Edition, TI84 Plus, TI84 Plus Second Edition, TI89, TI89 Titanium, TI92 Plus and Voyage 200 calculators.
*Please remember to read the ROM section below before downloading this application!
It will turn your phone or tablet into an exact replica of your calculator. The emulator will provide the same functionality and generate the same results as your real calculator. Being ported to Android means that it will always fit in your pocket, have a backlight, be rechargeable and also run faster.
You would be able to install applications by copying the App file to the internal memory of your phone, pressing the 'Back' button and selecting 'Install Application/Send File'.
Graph89 would be great tool for math, science and engineering courses in high school, college and beyond. Some of these calculators feature Computer Algebra System (CAS) having the capability to simplify and symbolically solve mathematical expressions.
Graph89 combines two powerful emulation engines which make it the only app in the Android Play Store to support the full range of TI graphing calculators.
1) TiEmu  http://lpg.ticalc.org/prj_tiemu providing support for the Motorola 68K family: TI89, TI89 Titanium, TI92 Plus, Voyage 200
2) TilEm  http://lpg.ticalc.org/prj_tilem providing support for the Z80 family: TI 83, TI 83+, TI 83+ SE, TI 84+, TI 84+ SE
!!! IMPORTANT !!!
ROM:
Emulators are computer software which simulate a specific hardware. In order for the emulator to do anything useful it needs some software to run. The software that runs in your calculator (ROM) is copyrighted by TI, and as such, it can not be distributed by Graph89 or any other emulator for that fact.
This means that you will have to provide the ROM file yourself by extracting it from your own calculator. Transfer it to your phone, and then tell Graph89 where to find it. To extract the ROM you can follow the instructions from http://www.ticalc.org/programming/emulators/romdump.html and by using TiLPII from http://sourceforge.net/projects/tilp/files Google and youtube are also great sources of tutorials and help.
Wabbitemu http://wabbit.codeplex.com/ is also a great tool for extracting the ROM from your TI83/TI84
Supported ROM files:
TI89, TI89 Titanium, TI92 Plus and Voyage 200:
*.rom, *.89u, *.v2u, *.9xu, *.tib
TI83 Plus, TI83 Plus SE, TI84 Plus and TI84 Plus SE:
*.rom, *.8Xu
TI83:
*.rom
Firmware updates (*.89u, 9xu, *.v2u, *.8Xu) which are normally used to restore the operating system of your calculator can also be used as a ROM image.
Needless to say, you will be very disappointed if you purchase Graph89 without having the ROM file ready. You will just see some instructions and a blank screen.

Graph89 needs permission to look at your Android Account in order to generate a unique ID shown under F1/About. This works only for TI89/V200. Note that there is no internet connection required for this App.
TiEmu, TilEm and Graph89 have been developed independently of Texas Instruments and are not affiliated with TI.
Texas Instruments and TI are trademarks of Texas Instruments Incorporated.
