On Android you can use a lot of programming languages inside Termux[0]. It is a terminal environment with a package manager. I'm mostly using it for writing small automation bash scripts and a little for Nim programming. What surprised me is the fact that Termux always ships the latest version of Nim. They're practically the first to update the compiler on new version release, even compared to rolling Linux distros, OpenSUSE Tumbleweed and Arch taking second and third place after a week or two. I also have full blown Neovim IDE configured for Nim. In combination with a custom 7-row keyboard[1] it's even somewhat comfortable to use for a quarter of an hour =).

Termux. I love terminals, and to have one on the go is a godsend. I use it for all kinds of things like password storing (my own custom little program[1]), `dict` for looking up some english words, reading man pages during long train rides, managing my VPS through ssh, `ncdu` for clearing up some storage space. I use aria2 cli to download big files often 10 times faster than standard android download system. If I have to write a small code snippet - I have python and nim installed and always at hand with almost full ide support in neovim. I use completely configurable custom keyboard app[2] with full set of keys[3], so coding on it is a breeze.

Not sure what you mean by modal keyboard, but there is fully customizable row of keys in termux. I disabled it, because I use special android keyboard app[0] with a custom layout made from scratch[1]: all common symbols, arrows, esc, ctrl, alt, forward delete, paste and enter gestures etc. etc. [0] - https://jbak2.ucoz.net/ (yes it's horrible website, but it's free and easy to maintain for the handicapped developer) [1] - https://github.com/Archargelod/jbak2Templates-Skins
