Get a TI-82, TI-83, TI-83+, TI-85, AND TI-86 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 TI-8X 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 TI-82 is designed for algebra and trigonometry. Graph and compare functions, perform variable substitution, and solve single variable equations.

The TI-83 is designed for statistics and trigonometry. Graph and compare functions, and perform data plotting and analysis.

The TI-85 is great for engineering and computer science. Graph and compare functions, perform bit manipulation and convert between numeric bases.

The TI-86 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 TI-BASIC and perform basic scientific calculator operations.

AlmostTI turns your Android device into a Texas Instruments graphing calculator. It fully emulates TI-84+, TI-84+ Silver Edition, TI-83+, TI-83+ Silver Edition, TI-73, TI-83, TI-85, TI-86, TI-82, and TI-81 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

TI-85.ROM, TI-86.ROM, TI-81.ROM, TI-82.ROM, TI-73.ROM, TI-83.ROM, TI-83P.ROM, TI-83SE.ROM, TI-84P.ROM, TI-84SE.ROM

For information on dumping a ROM from your own calculator, see here:

Wabbitemu creates a Texas Instruments graphing calculator right on your Android device. Fast and convenient, Wabbitemu allows you to always have your trusty calculator with you. Because Wabbitemu is an emulator, the calculator it creates will act exactly like the real thing. Wabbitemu supports the TI-73, TI-81, TI-82, TI-83, TI-83 Plus, TI-83 Plus Silver Edition, TI-84 Plus, TI-84 Plus Silver Edition, TI-85, and TI-86.

Wabbitemu, like all emulators, requires a ROM image. Wabbitemu includes an easy to use setup wizard that will help you create a ROM image for your TI.

GraphIt is a utility that is used to display on a Cartesian plane any mathematical function, which can be f(x)=2, f(x)=2*x, f(x)=sin(x) ecc... The management function is entrusted to you: you can add more or modify existing ones.

The integration of functions is facilitated by self-completion 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 is an emulator for the TI-83, TI-83 Plus, TI-83 Plus Second Edition, TI-84 Plus, TI-84 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.
