@smith.adriane as finicky as Apple’s approval process is, I think a demo app should be OK in the App Store: https://developer.apple.com/support/downloads/terms/apple-developer-program/Apple-Developer-Program-License-Agreement-20210607-English.pdf

I thought the issue would be allowing scripting

Section 3.3.2; It explicitly allows interpreted code (as long as it doesn’t change the purpose of the app) and even executable code, if the app is a programming environment…

that would certainly be cool

Mike Fikes has had a REPL app for a long time; The method you’re currently using would not be regarded as executable code, correct?

It’s more like “scripting”, if I’m understanding fully.

yea

do you have link to the repl app?

there are some weird stipulations: > (i) no more than 80 percent of the Application’s viewing area or screen may be taken over with executable code, except as otherwise permitted in the Documentation,

neat!
