I have a derive.exe from 1996 that I still use. TI's calculator, as an incredibly fast windows app that's like 20% of wolframalpha.
And to think on all "modern" OSes you can't even do that. Neither Android nor IOS let you do this in any way shape or form. Even with portable webapps it doesn't work, as webapps go offline. And microsoft clearly wants to create this situation too (last brute force attempt was windows home)

you can also "add to homescreen" on iOS/android and it acts like a native app & works offline. symbolic math - computer algebra system, integration/differentiation, finance app in rom, 3d graphs.
(emu is not my work, i only packaged it for PWA and host it for myself to use, but you are welcome to as well)
Derive is more sophisticated. TI-89/92/Nspire is close though.
Derive doesn’t run on my iPhone sadly
Sure (and thanks for the link, do you have a TI-82 as well?) but it won't "last". You'll take the site offline, sooner or later and I can't just store an exe locally and use it in 20 years. I'll lose the ability to install it on phones.
That is my personal site, I do not expect to take it down, since that is where I post my projects. But also, you can just save it from there entirely, and serve from your own site -- there is no server-side part to it.
no 82. I only liked the ti-89
