Excellent All Around Got this going in no time at all thanks to TI having a free download of their 89 rom. Played with it for a while and it runs beautifully! Only problem I've seen is a lot of flashing on the screen playing assembly games, (my primary use for my ti89 in calculus class was games... (: ) Any idea what causes that? I'd love to play calcrogue again... but it's giving me a headache, lol!

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!

Incredibly Simple I have a TI89 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 TI89, 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!

Fantastic emulator This is a wonderful tool. The application is extremely easy to use, even though the calculator it is emulating is a beast to wield. TI has the latest updates for the ROMs on their website, so you can quickly find and download the latest version. Easiest emulator I've ever used by far.

Very good implementation If only Texas Instruments did provide a way to purchase a copy of the ROM legally, this might be even better than the real hardware. Obviously one gets better haptic feedback with real buttons but otherwise emulated hardware is better (better screen viewing angles, possibly better performance than with real hardware).

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
Nostalgia Makes me want to dig my 89 Titanium out of the closet and play with it again. The 89/92 series of graphic calculators were very powerful handheld machines in their time, and now we live in a world where cellphones can run them. Good work but has one problem so far, when sending a file, and it's already on the calc, then the app crashes.
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?
Works Perfectly, and Open Source To Boot! The TI89 interface is nothing like the interface on the TI83 and 84, and a poor reason to rate the app with one star. The CAS and 3D graphing capability alone make the calculator more advanced than the 83 and 84. Whether the 89 is better than the 83 or 84 is a matter of debate. As to the app itself, its best feature is the ability to install apps to the "flash memory" of the calculator, allowing the emulator to use the apps that come standard on the TI89 Titanium, including the stats and list editor. A minor complaint, and one that does not merit a reduction in rating, is that the TI89 Titanium keypad is too bright, thanks to TI using a "Titanium" finish. I've fixed this in my copy of the app, built from source.
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!
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!
Excelente. The best app for engineer student Perfecta en SG Note con ICS
Too much work! I have a TI 84 PLUS. I got the app so I wouldn't have to pull the calculator out all the time and when I forgot to bring it with me to school I could still get my work done....it's big and clunky and my phone isn't! But they want you to download the software which is stupid. I got the app for convenience now you want me to do extra steps! Not worth the time! I'll download another app that's more convenient!
Best app ever You need a tablet to be able to see the buttons but if you've got one, this totally works as a graphing calculator. Helps me so much! (later edit) loses one star for the file transfer feature having problems. Won't let you upload more than one file to the calculator's memory at a time without locking up. Irrelevant bug if you dont use that feature as most people dont.

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, 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.
Frequently Asked Questions:
1. How do I bring up the menu?
You can bring up the menu by swiping from the left edge of the screen, or pressing the menu key (if your device has one).
2. How do I disable vibration when I tap on a button?
Open the menu and click on settings. Under the 'Skin' category unselect 'Vibrate on keypress'
3. How do I load apps like PlySmlt2 or Inequalz?
To load any file to your calculator you need to first download it to your SD card or internal storage on your device. You can find the official TI applications for the 84 Plus (non color) available here: http://education.ti.com/en/us/software/search/ti84plusfamilyti83plusfamily#view=mathapps. Once you have downloaded the app to your device open Wabbitemu. Swipe from the left edeg of the screen to bring up the menu, and select 'Load file'. Find the file you just downloaded in the list and select it. The file will be sent to your calculator. Apps for the 83+ and 84+ calcs will end in *.8xk. Apps for the 84+CSE will end in *.8ck or *.8xk.
4. I'm missing fraction options when I press Alpha+F1! How do I get these fraction options?
Fraction options (and the rest of the Alpha+FN menus) are only available on OS 2.55 MP. Wabbitemu allows you to download both 2.43 and 2.55 MP. You can check your OS version by hitting '2nd' then '+'. Then press enter to go to the about screen. If it not 2.55 MP or 2.53 MP you will need to upgrade.
To upgrade you will need to recreate your ROM by going through the setup wizard again. The setup wizard is runnable if you bring up the menu by swiping from the left edge of the screen. Then select 'Rerun setup wizard'. As you go through the setup make sure you have selected OS 2.55 MP on the OS selection screen.

Free Graphing Calculator
Does far more than most of the paid calculators out there . . . let alone the free ones.
Features:
1) Scientific Calculator. Simple to grasp and easy to use, but powerful features are available when you need them. Available functions include the following:
• the usual arithmetic functions and exponentiation.
• square root, cube root, nth root, natural log, log base 10, log of arbitrary base, absolute value, factorial, permutations (nPr), combinations (nCr), modulus, random integer, bell curve, cumulative normal distribution, decimal to fraction.
2) Graphing. Capabilities:
• Graph up to four equations at once.
• Graphs are labeled.
• You can drag the graph or pinch to zoom in or out.
• Calculator can find roots and intersections.
• Graph in polar coordinates.
• Graph parametric equations
3) A unit converter. With a tap, you can enter the result of your conversion into the calculator. Currently converts different units of the following: acceleration, angle, area, density, distance, energy, force, mass, power, pressure, speed, temperature, time, and volume. Great for doing physics homework!
4) Constants for scientific calculations  speed of light, strength of gravity at Earth's surface, etc. etc. etc. Tapping on a constant will insert it into your calculation  i.e, you don't have to key in the value. Again, great for doing physics homework!
5) It can make a table of the values of any function you care to enter. You can choose the starting x value of the table, as well as how much x increases for each successive row.
6) Forgot the quadratic formula? Or the doubleangle formulas for sine and cosine? The math/science reference hits the high points of various subjects. Currently includes algebra, differential and integral calculus, geometry, trigonometry, vectors, vector calculus, and classical mechanics.

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 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)
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.
