Coming soon to the App Store

Two parents.
One baby. One thread.

RelayBaby is the baby tracker built around the handoff. Log feeds, sleep, diapers, and medication once, and the next caregiver walks in already up to speed.

The problem

Scattered texts.
Tired memory.
Sticky notes on the fridge.

Parents and caregivers shouldn’t have to thread together baby care across three group chats and a half-remembered conversation at the door.

RelayBaby gives your household one shared timeline, so whoever is on duty always knows what just happened, what’s next, and where to pick up.

What it holds

One quiet place
for the whole day.

No upsells inside the app, no charts that need a degree to read. Built for the realities of newborn nights, daycare drop-offs, and shared parenting.

  1. 01

    Feeds

    Breast, bottle, or solids. Times, volumes, and side switching are handled for you. No spreadsheets, no math at 3 AM.

  2. 02

    Sleep

    Tap to start, tap to stop. Naps and overnight roll up into a calm summary the next caregiver can read in a glance.

  3. 03

    Diapers

    Wet, dirty, mixed. Quick notes for the next person on duty: mood, milestones, the thing you don’t want to forget.

  4. 04

    Medication

    Log doses and set reminders once. Your Care Circle sees the reminder, knows who gave the last one, and never doubles up.

  5. 05

    Handoffs

    When the next caregiver takes over, they see the last feed, the last nap, the open reminders, and the one note you wrote.

  6. 06

    Care Circle

    Partner, grandparent, nanny, family helper. Everyone on the same timeline, in real time, on the same iPhone app.

The relay

Care passes cleanly,
the way a baton does.

Most baby trackers log the day. RelayBaby is built around the moment that actually matters: when one set of hands becomes another. The handoff.

How Care Circle worksSee a real handoff
  1. 01

    Invite the people who actually help.

    Partner, grandparent, nanny, family helper. Roles are tidy, invites take seconds, nobody gets a paywall in the middle of a tantrum.

  2. 02

    One shared timeline, always live.

    Feeds, sleep, diapers, medication, notes. Whoever opens the app sees the same picture, in real time, across iPhones.

  3. 03

    Hand off with the full context.

    The next caregiver doesn’t inherit a guess. They see the last feed, the last nap, the open reminders, and the one note you wrote.

How it works

The day, in three moves.

A simple loop that fits real life with a baby. Log, read, hand off.

  1. Log it in seconds.

    Tap to log feeds, sleep, diapers, medication, or a quick note. No menus, no hunting.

  2. Read it in a glance.

    The day rolls up into a calm timeline with the totals that actually matter at 3 AM.

  3. Hand it off cleanly.

    When the next caregiver opens the app, they inherit the full picture, not a guess.

We built RelayBaby because at 3 AM, with a newborn and a partner asleep, no app we tried answered the only question that mattered: what happened in the last four hours? So we built the one that does.
The RelayBaby team. Built by parents, for the households doing this together.
