Termux
Another one of the tools of my trade these days is an awesome tool that I use on Android called Termux.
I've found all of the SSH clients on Android lacking in one way or another. I have a pretty peculiar setup with Docker, TMux and other tools and none of them worked quote correctly.
Enter Termux. I've not found anything that works quite as well with my development flow as Termux. I'm able to use the shell that I want to, install MoSh and other tools and it just works. I'm able to connect from my phone when I need to and my tablet other times. It's my perfect compliment for work when I'm not on my desktop. Thank you, Jonas Fornwall, for an app that finally works.
I've donated. Why don't you try it as well and send a donation Jonas' way.
