Anyone have a good app/tool to manage responsibilities and essential info?

We’ve had a few nannies over the years and every time there’s change over, we have to re-establish all the lists of things. I’m curious if you know of a tool for this.

I’m looking for a simple app or way to do a few things…

  • Recurring tasks (change kids beds, straighten the playroom, prep their food, etc.)
  • Medical information
  • Quick link to emergency contacts
  • Addresses for local folks
  • Parks we like
  • Behavioral flags
  • Household procedures (how-tos)

Things like that. Any ideas?
