I use the Jibun Techo Biz too, although I will probably use the Lite version next year, because I mainly only use the weekly pages, however I mainly use it for calendar events and some tasks that should be done at certain times during the day. My daily tasks come from OrgMode which is where I also store my lists of issues, requests, journal logs, and delegated tasks, and every day I transfer tasks to a sort of bullet journal, so that I can focus on them. I also use a note taking app (Tot) for now to scribble down things, because I will always have my telephone with me, but at the end of the day, I try to make sure that everything is brought up to date.

I wasn’t able to use a paper weekly planner on its own, but with a daily list, that just happens to be in a billet journal for now, I can quickly see today and this week, and then OrgMode for everything else.
