Yeah but it sucks. There's a button in its settings to install a Debian chroot environment; gave it a go and it bricked itself, had to clear the app's storage and factory reset it.
Add to this list that it tends to not work while connected via a VPN. Not sure why but this makes me very skeptical of it.
Yeah, I can always use the Android Terminal once. If I re-open it, it says it's corrupted, and has to delete and re-install its minimal Debian environment.
