This app is exactly what I have been looking for. I have tried other apps that offer bits and pieces of system admin tools  and they were not great. This one just gives me what I need: a bash prompt and the ability to easily install various components with apt. As a bonus  I also get a nice python 3.6 system to use as I need  and a sshd server to connect to my phone from my other systems.
