The key caveat being that iSH does x86 emulation to achieve this, but otherwise it seems to looks pretty darn nice. I have yet to try it but now that I've switched over to iOS I may just download it to compare usage vs Termux.
I find it usable as a text editor, git client and ssh client, which is great really. Any lightweight CLI usage should feel great.
I was hoping to run go and python code locally, but even installing deps, not to mention running tests is unreliably slow.
