FlowCE: Calculus on your TI-84 Plus CE

I wonder who would install this onto their calculator in earnest. Like, who’s the segment of folks with the savvy to learn about this and install this on their TI calculator, but who aren’t savvy enough to just learn to do the computations in curricular calculus class?

I can run Maxima on my phone. Heaven!

Snap judgment, but it appears to be a vibe coded interface added to an existing CAS for a TI-84 Plus CE calculator.

Can a Ti-85 do this?
