They’re as close as you’re going to get to a hardware graphing calculator on your iPhone or ipad, even if they aren’t direct copies of your graphing calculator’s UI and features.

You can leave the TI graphing calculator at home thanks to this web-based TI-83 and TI-84 emulator. As with pretty much all emulators, this depends on a ROM image from the actual hardware to work.

The graphing calculator reached a kind of technological plateau in the late 1990s. At least that's what Amazon consumers are saying. Right behind the TI-83 Plus is the TI-84 Plus, released in 2004.

A popular modder on YouTube created the ultimate cheating device by putting ChatGPT on an old graphing calculator.

Ti's graphing calculator technology is ancient -- older models, like the Ti-83 and 84 can't draw certain lines accurately, thanks to screen resolution limitations -- but they get the job done.
