What makes RelayBaby different

  • Built for shared care. Most baby trackers assume one parent on one phone. RelayBaby assumes a household, partners, grandparents, caregivers, all on the same page.
  • Calm by design. No noisy badges, no upsell popups, no dark patterns. A premium app that respects exhausted parents.
  • Caregiver handoff. Hand off care without losing context. The next caregiver sees the last feed, last nap, and open reminders at a glance.
  • Private to your Care Circle.Your baby’s data is shared only with people you invite.
