Install other programs on raspbian

[wsedits01]

Can this app only be used for PiHole installation? Or can I use other programs inside it? My idea is to make a Home server with an Android phone that I no longer use, could I install Qbittorrent on raspbian for example?

Yes you should be able to install pretty much anything.
Keep in mind that any package that creates a user account will need to be added to the aid_inet group:
sudo usermod -a -G aid_inet qbtuser

Also, because systemd isn't available you can add something like this to /etc/crontab so qBittorrent starts automatically with the instance:
@reboot root systemctl start qbittorrent-nox@qbtuser
