Marlow is a shared baby-care diary for sitters, helpers, and invited parents. Log the day in a few taps: - Sleep and naps - Bottles and feeds - Diapers - Mood - Medicine - Notes, allergies, and routines Sitters can add babies, organize rooms when needed, invite helpers, and keep each child's care notes in one place. Parents get a read-only view of their baby's day, including the current status, recent activity, allergies, care notes, and patterns over time. Marlow is built for independent sitters, nanny shares, and small care groups that want organized parent updates without a heavy daycare management system. Parents join only by invite. Children do not create accounts. Subscriptions are paid by the care diary owner through Apple in-app purchase; parents and helpers use Marlow for free. Terms of Use: https://marlow.care/terms
