I use my phone for some things, but our master calendar is a wall calendar that hangs in our kitchen and holds all of our appointments, dates, birthdays, etc. For daily lists and planning I have a computer printed page with a master 'daily' list on one side and a 'deeper clean' list on the other side, and it's slipped into a plastic sheet so I can dry erase the items off of the list or add items to the bottoms (then erase all marks and start over the next day). For menu planning I use a note my phone, then write out just the week we're in on our kitchen chalkboard.
