The "Activity" section in Moleskine Journal is designed to display the routines, tasks, and calendars created in Moleskine Planner.
We envisioned this space as a way to track routines made in Planner and comment on them through the notes section.
For example, if you create a recurring activity in Planner like:
"RUN every week on Mon, Wed, Fri, Sun",
you’ll be able to see the weekly overview of that routine in Journal and add personal notes or reflections to each session.
