Hah, I guess the Internet really is like a sewer, you have to have good protective equipment to wade in it...
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)
no 82. I only liked the ti-89
