@peaoPerdido @jeremy I routinely use #Emacs with #OrgMode and #OrgRoam on #GrapheneOS (a security hardened Android fork). I can even use #OrRoamUI and see the node cloud in my Vanadium browser. The setup instructions are a little knarly though
Android ports for GNU Emacs https://sourceforge.net/projects/android-ports-for-gnu-emacs/files/termux/
Having some good keyboards like The Unexpected Keyboard https://f-droid.org/packages/juloo.keyboard2/ is critical to be able to use the Emacs key combinations.
I also use #SyncThing to keep my notes in sync across devices.
