GNOME Console (formerly King's Cross) is a terminal emulator intended for use with GNOME/Phosh. It is intended to be a simpler alternative to GNOME's default terminal and Tilix and works great with phones.
GNOME Console is available in Alpine's Community repository and can as such be installed as follows:
# apk add gnome-console
On postmarketOS v21.12 and earlier, GNOME Console is known as kgx as it uses the old name there.
# apk add kgx
