Fool your friends by handing them your calculator with this enabled, and watch their reaction when they hit solve.


This is roughly from TI84Calcwiz's site!


Downloading apps and programs onto your TI-84 graphing calculator can extend its abilities, help you gain an edge over your competition in high-stakes tests, or even let you play games on your calculator.

This guide applies to every TI-84, including the TI-84 Plus CE, TI-84 Plus, TI-84 Plus C Silver Edition, and TI-84 Plus Silver Edition calculators.

Getting Started

What You Need

Any TI-84 Plus Graphing Calculator
Calculator Charging Cable (Mini USB)
TI Connect CE Software (Download Here)

Quick Warning

Make sure you install TI Connect CE! You can't transfer any programs to your calculator without it.



TICalc.org: TICalc.org has the largest selection of math/science programs, as anyone is able to upload.
TI84Calc.dev: TI84Calc.dev is the best for easy-to-use, simple, and helpful programs from a fellow student.
TI84CalcWiz.com: TI84CalcWiz.com is the best for games with a quick, painless installation process.
TI.com: The Texas Instruments website is the best for high quality apps, but has a relatively small selection.


All the websites are quite simple to navigate, except for TICalc.org, which can be a bit confusing for beginners. For it, click on the link above and choose your calculator. From there, click on basic, then choose a category, either math, science, or even games. You can then download any program you find interesting by clicking on its name.


Step 1

Some downloads come in the form of a .zip file. This means that you need to extract the contents before continuing. To do this, open the .zip file and drag all of the files inside onto your Desktop. If the program instead comes in the form of a .8xg or a .8xp file, move the file to your Desktop. No need to extract first!

Step 2

Open TI Connect CE, and click the Calculator Explorer tab on the sidebar. This is the second option under the camera. Plug your calculator into your computer using your charging cable, then make sure it is on.

Step 3

You should now see a list of all of the files on your calculator. Drag all of the downloaded files into the list to send them to your calculator. A window should now pop up. Click SEND to send the program to your calculator.

If no window showed up when dragging in the files: you can manually browse to the file you downloaded by clicking Actions in the top bar, and then “Add files from computer…”

Step 4

If everything worked out, the program/app should now be on your calculator! See below for how to launch it.


Programs and apps are stored under two different places on TI-84 calculators. If you are unsure whether the file you downloaded is an app or program, just check both locations.


Press the [apps] button on your calculator, and select the app you would like to use from the menu.


Press the [prgm] button on your calculator, select the program you want to use, and then press enter to run it.



If you get “Error: Invalid”, this means you have a newer operating system that disables the ability to run games.

If you get an “Error: Syntax” or an “Error: Archived”, this means you need to update your operating system.


To exit the game, simply press [del], [mode], [clear], or [on].

To delete a program, Press [2nd], [+], [2], [7], and then selected the program you want to delete and confirm.


Questions? Comments? Suggestions?

Feel free to contact me for any questions, comments, or suggestions. I will try to respond to every email or DM I get, but keep in mind that these programs are provided under the MIT license. Also, feel free to modify my programs as desired, but I would highly appreciated if I was still credited as the original author if redistributed.


Quick Information!

This website showcases the TI 84 Calculator programs created by Sachin Agrawal. I'm a self-taught programmer who knows many languages and I'm into app, game, and web development. I got my TI 84+ CE in 6th grade, and have been creating programs for it ever since, with an emphasis on improving functionality and speeding up calculations, especially for higher level math classes beyond Calculus.

In my free time, I like to play the popular block-based videogame Minecraft. I have a small YouTube channel featuring that content. Please consider subscribing if you like my calculator programs, as it really helps me out: youtube.com/@scinovuscrafted.
