Everyone who helps. 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.
Coming soon to the App Store for iPhone. One email, on launch day.
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 is a shared baby tracker for iPhone. It gives your household one shared timeline, so whoever is on duty always knows what just happened, what’s next, and where to pick up.
3 AM. One hand free.
Tap to log feeds, sleep, diapers, medication, or a quick note. No menus, no hunting, no math in the dark.
- Feeds
- Breast, bottle, or solids. Times, amounts and which side, in a few taps.
- Sleep
- Tap to start, tap to stop. Naps and overnight roll up into one summary.
- Diapers
- Wet, dirty, mixed. Backdate it when you forget mid-routine.
- Medication
- Log doses and set reminders. In a Care Circle, everyone sees who gave the last dose and when.
- Notes
- Mood, milestones, the thing you don’t want the next person to miss.
Care passes cleanly, the way a baton does.
Many baby trackers log the day. RelayBaby is built around the moment that actually matters: when one set of hands becomes another. The next caregiver doesn’t inherit a guess. They see the last feed and the last sleep with who and when, and the notes from your shift.
See how a handoff works
By daylight, the whole day has names on it.
The day rolls up into a calm timeline: totals at the top, every entry below, and who logged each one. Whoever opens the app sees the same picture, synced across iPhones.
One plan. Six people. Nobody else pays.
