Is there a way that I can do programming on my phone?

I have installed Carnets, Pythonista and Lua Studio on the new iPad. I don’t know how useful they (or anything else) would be on a phone.

In my scripting folder, I have a-shell and Processing.

Carnets is a stand-alone Jupyter notebook.

A Redditor suggests a Raspberry Pi, if available, and if the laptop in the article can’t be revived. I can’t speak to that.

Pocket PHP on Android is free, includes an editor and will run as a rudimentary server on a local network (or usable on your own phone).

I'm sure there is. Probably more than one way. But why would someone want to code using their phone? As someone once pointed out, just because you can doesn't mean you should.
