Planner in my pack for my month-to-month.
Notepad on my phone for week-to-week.
Mini-journal in my pocket started for my day-to-day just last week thanks to your posting it in a pubski. This has been super helpful in prioritizing my day. I tried a few times making an "A" and "B" priority list in my phone to no avail.
The notepad in my phone has LOTS of on-going thoughts, ideas, and to-do's. Many times I write in my phone, then print them out to go into my physical journal at home [for when I want to vent, ruminate, or explore an idea or event].
