AlmostTI - TI Calc Emulator

Garage Research Emulators

About this app

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

Ratings and reviews

Excellent emulator. I greatly prefer the UI of TI graphing calculators, so it is really nice to have the "real" experience. My ONLY gripe is that I cannot find any way to import files to the calculators. I have many programs on my physical calculator that I wish I could import to this emulator. I can use TI software to download the files off my physical calculator, but there doesn't seem to be any way to import those files to this emulator.

Almost exactly what I needed, but a bug makes it too frustrating to use. Any time I press a key there's a chance that it randomly doesn't register in the calc (it still vibrates on keypress so it should have been received). This means I can't be sure what I typed is what's on screen without checking every time. Would love to repurchase if this bug is fixed, I love everything else about the app Edit: I was using 83 and 84+ models, both were affected

I previously used AndieGraph which my last update no longer allows it to run. Even though there isn't any Permissions being blocked it prompts "Unless you grant AlmostTI all required permissions, it..." Each time I run the app. Also when selecting the 2nd key and Off option it disables button but doesn't close the app. Will there be an update to run TI-92?

What's new

* Removed missing permissions warning.
* Switched to Android-34 SDK (Android 14).
* Switched to the latest NDK, Gradle, and tools.
