Alternatives to "shell in a box" web client that work for mobile? Want a web-available shell client for personal server.

Hey . It was easy to setup as a daemon with an nginx reverse proxy to it (behind auth ofc), but interactions via mobile chrome are so horrendous it's unusable.

Anyone know of similar software that they've used successfully with mobile browsers?

I'm aware I could just use a terminal app and ssh on my phone, but my current Android phone doesn't have root or ssh and I'm too lazy atm to find the oh-so-specific sacrificial ritual and incantations required to unlock superuser for this model phone.
