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.

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

In certain contexts such as higher education, scientific calculators have been superseded by graphing calculators, which offer a superset of scientific calculator functionality along with the ability to graph input data and write and store programs for the device. There is also some overlap with the financial calculator market.
Modern scientific calculators generally have many more features than a standard four or five-function calculator, and the feature set differs between manufacturers and models; however, the defining features of a scientific calculator include:
floating point arithmetic
logarithmic functions, using both base 10 and base e
trigonometric functions (some including hyperbolic trigonometry)
exponential functions and roots beyond the square root
quick access to constants such as pi and e
In addition, high-end scientific calculators will include:
hexadecimal, binary, and octal calculations, including basic Boolean math
statistics and probability calculations
programmability — see Programmable calculator
conversion of units
While most scientific models have traditionally used a single-line display similar to traditional pocket calculators, many of them have at the very least more digits (10 to 12), sometimes with extra digits for the floating point exponent. A few have multi-line displays, with some recent models from Hewlett-Packard, Texas Instruments, Casio, Sharp, and Canon using dot matrix displays similar to those found on graphing calculators.

Boost your math score on the ACT test and SAT test by programming your TI 83/84 with these totally allowed (see ACT/SAT rules and regs on their website) sneaky, super easy-to-program calculator programs. We give you step-by-step directions and show you how to use them on real ACT and SAT test questions.
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).
The following mathematical functions are available:
polynomials, rational functions, trigonometric functions, inverse trigonometric functions, hyperbolic functions, natural logarithm, exponential function and all the possible combinations of them.
Best math tool for school and college! If you are a student, it will help you to learn calculus (analysis) and algebra!
Note: Mathematical analysis is a branch of mathematics that includes the theories of differentiation, integration, measure, limits, infinite series and analytic functions. It can be applied to physics, economics and engineering.

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 !!!
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:
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.
An 8Xu (firmware update) file can now be used as a ROM for TI84+, TI84+SE, TI83+ and TI83+SE
Added support for: TI-83, TI-83 Plus, TI-83 Plus SE, TI-84 Plus and TI-84 Plus Second Edition using the TilEm2.00 engine.
