Fambul is a family app for running the week together. It holds tasks, school runs, and team schedules, and it reads the calendars you already use instead of asking you to move into a new one. It's really for handing a piece of the week to someone else, your partner, a grandparent, the sitter, with everything they need attached, so it stops living in one person's head. Caregiver roles can see only the hours they're covering.
