I have been a SOD user from the kickstarter days, and I have used both the paper and digital versions. When I needed an Ipad and apple pencil for work, I decided to try the digital version of the planner. I use the GoodNotes app and open the PDF file there. I can write, highlight, add pages between SOD pages for notes / planning, bookmark pages, add calendars to an outline, etc. It is easy for me to carry with me everywhere I go.
My practice is to wake up early - before the husband and kids - take my caffeine to the back porch, and spend 15 or 20 minutes working through my day. Having the planner has kept me feeling grounded in a time of uncertainty.
