Marlow Diary
Read full descriptionHide full description
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
SitterSheet

Leave clear instructions, not another long message. SitterSheet turns your family's saved details into a visit-specific handover that your babysitter can read without installing an app. YOUR FAMILY LIBRARY Keep meals, comfort items, routines, bedtime steps, allergy and medication instructions, contact numbers and house notes together. Search the library when you need a detail quickly. A readiness checklist points out missing information; always confirm important instructions with your sitter. PREPARE EACH VISIT Plan the date and return time, add instructions for that visit and reuse your usual plan as a template. Keep a preparation checklist for each visit and see timed routines together. Review family details that changed since the last shared handover. PREVIEW, THEN SHARE Choose the children, contacts and house notes to include. Select a compact or detailed layout, review every page in the PDF preview, then share that same document or print it using the system share menu. Allergy and care instructions stay with each included child. FREE AND PRO Free includes one child profile and the family contact and house-note library. Existing records remain readable and editable. Pro adds more child profiles, PDF preview and export options, visit plans and templates, saved visit checklists, the routine timeline and handover-change comparison. Monthly, yearly and one-time lifetime options unlock the same Pro features. Subscriptions renew automatically unless cancelled at least 24 hours before the current period ends. Manage subscriptions in your App Store account settings. Restore Purchases is in Settings. Existing legitimate lifetime purchases remain valid. PRIVATE FAMILY INFORMATION Care instructions, child notes, routines, contact notes and visits stay on this device and are excluded from device backups. Only basic child details, contact details and house notes can sync through your private iCloud. Check local care information on the device used to prepare the PDF and keep an independent copy of essential instructions. No advertising or tracking SDKs. You choose what to share. Support requests send your message, reply details and app/device diagnostics to our support service. SitterSheet organizes family-provided information. It does not provide childcare, medical advice or emergency monitoring. Keep essential instructions available independently and check them with the responsible adults.
