Are there any? I could find proprietary apps doing it from Google’s PlayStore but I really rather use a FOSS alternative if there are any. I tried searching on F-Droid and I couldn’t find any.
Joplin is FOSS & supports live LaTeX. The editor is markdown & you use $ for inline LaTeX & $$ for full line.
They’ve got both desktop & mobile versions. One of my favorite apps.
I can’t help you, but I am curious about your use case. I would hate to write a LaTeX document on my phone :p
Maybe Termux and vim/nano
Don’t you need to give Termux too many permissions (for obvious reasons and well justified sincd it’s a terminal emulator)? That’s the only thing keeping me away from Termux, I’m not very familiar with it and I don’t feel comfortable going ahead onto an app like that since I’d use it exclusively for this purpose. Thanks for the suggestion though (I didn’t know you could run vim/nano from there, interesting, by the way). For anyone reading this and don’t think this way I do and want to give it a try, here are some Termux official webpages:
