Yeah I have termux which is kinda like Linux, however I needed root permissions to use sudo command for installing Linux apps, I don't trust anything that asks me for root. Doesn't feel safe, maybe it is? Idk.
But I needed to update /install something called ruby 2.3 since it isn't in my termux??? Idk if the app will have it too.
I found a website that is called homebrew formula, for linux it told me to use their repository to use their brew command and install bchunk.
If only I could figure out how to instal bchunk on termux or even linux if I can get the app you said to work etc
But yeah seems risky.
