Luki is a baby tracker built to help parents, nannies, and caregivers stay on the same page. Instead of trying to remember when your baby last fed, slept, had a diaper change, or took medicine, Luki keeps your baby’s care routine organized in one simple shared space. Whether you are caring for a newborn, sharing responsibilities with your partner, leaving updates for a nanny, or checking what happened while you were away, Luki helps make baby care feel clearer and less scattered. With Luki, you can: • Track feeds, diapers, sleep, medicine, and notes • See your baby’s latest care activity in one timeline • Share your baby’s care space with family and caregivers • Keep everyone updated without constant messages • Record measurements and vaccine details • Create clearer handoffs between caregivers • Understand your baby’s routine over time Luki is made for families who want a baby tracker that feels simple, modern, and practical. No complicated setup. No messy notes. No repeated “when was the last feed?” questions. Just a calmer way to track and share your baby’s daily care. Why Luki? Baby care often involves more than one person. Parents, nannies, grandparents, and family members may all help throughout the day. But when everyone is using memory, chat messages, or paper notes, important details can get lost. Luki helps reduce that confusion by giving your family one shared place for baby care updates. Everyone can see what happened recently, what was logged, and what needs attention next. Use Luki to: • Know when your baby last ate • Track diaper changes throughout the day • Record naps and sleep patterns • Leave notes for the next caregiver • Keep medicine and care details organized • Save vaccine and growth records • Make shared parenting and caregiver handoffs easier Luki is not about making baby care perfect. It is about making daily care easier to follow, easier to share, and easier to manage together. Download Luki and make shared baby care feel calmer.

Verdict
The clearest difference is update cadence: Luki at every 3 days against ContractionFlow's every 9 days. ContractionFlow's advantage is iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
