We use the calendar that comes with phone (also on my home computer). One for home, one for each member of the family. (Even use one to track my parents' busy travel scedule so I know where they are!)
Wunderlist is great - you can have deadlines, recurring chores, and sub-lists. I don't share it, but I think you can, You can also send emails of your lists etc if you want to.
Meal planning I use MealBoard. It takes a bit of setting up and I don't use the shopping part or full recipes but it is helpful whne you have that 'aargh!' I'm so bored of deciding what to cook moment.
