I am using Emacs on my Pine Phone running Mobian (Debian with a phone shell). What I am looking to do is set up Diary or Org-Mode to set up a calendar and get notifications when Emacs isn't running. I know there are a few things that can have you get a notification while running but I don't want to keep Emacs open all the time to preserve RAM and battery usage. Any ideas?
The reason I was hoping to use Emacs for this is because the default calendar isn't very mobile friendly (super small buttons) and somehow Emacs fits really well by default.
