BabyRelay

Shared baby care app · iPhone & Android

Every caregiver,
in the rhythm.

BabyRelay is a shared baby log for parents, partners, grandparents and nannies. Log sleep, feeds and diapers in a tap, and everyone looking after your baby sees the same live timeline, so no one has to ask “when did she last eat?”

How it works

Set up once. Everyone stays in step.

  1. 01

    Add your baby

    Name and birth date. Add more children any time, each with a timeline of their own.

  2. 02

    Invite your care team

    Send a six-character code or link. Caregivers install BabyRelay, enter the code and pick a name.

  3. 03

    Log and hand off

    Sleep, feeds, diapers and notes land on the same timeline for everyone, as they happen.

Features

A day and a night, relayed.

BabyRelay is built around handoffs, not charts. Here is what it does across one ordinary day.

  1. Sleep

    Asleep in one tap. Everyone knows.

    Tap when your baby falls asleep and a live timer starts for the whole care team. Forgot to tap? Log “woke 10 minutes ago”, adjust the start, or add a past sleep.

    On supported iPhones the sleep timer also shows on the Lock Screen and in the Dynamic Island, and other caregivers can get a shared sleep alert.

  2. Night wake · Feed · Diaper

    Log the night without waking up properly.

    Quick logs for feeds (bottle, nursing or solids), diapers (wet, dirty or both), night wakes and notes. Each entry records which child and which caregiver, so nobody has to ask in the morning.

  3. Next up

    See when the next nap window opens.

    BabyRelay suggests the next nap window from your baby’s age, today’s naps and bedtime, and explains where the number came from. A short nap trims the next wake window.

    Guidance only. It is not medical advice.

  4. Handoff

    Hand over in one screen.

    One screen with everything the next caregiver needs: when the baby last woke, naps so far, the last feed, when the next window opens and the latest notes.

    Share it as plain text to any messaging app, so a grandparent without BabyRelay still gets it.

  5. Care team

    One timeline for everyone who helps.

    Invite a partner, grandparent or nanny with a six-character code or a link. They join in the app and see every child’s timeline live, with a colour for who logged what.
