Built by tired parents, for tired parents

We built LunaLog after too many exhausted moments trying to remember the last feed, nap, or diaper change.

Our Story

My wife was tracking feeds and diapers with paper and pen, and I decided to build her a simple app to make that part of life easier. It started as something just for us, built around the real rhythm of caring for a newborn.

Then we kept adding to it. A faster way to log. Better handoffs. More visibility into sleep and daily patterns. Over time, that little tool we made for our own family turned into LunaLog as it exists today.

We built LunaLog for our family first. Now we hope it helps yours too.

Useful sleep insights from your baby's actual patterns

LunaLog helps you understand what is changing, what is improving, and what may be coming next.

"Your baby's afternoon naps are getting shorter. Try moving bedtime earlier by 20 minutes."

"Your baby feeds more frequently before longer naps - this is a strong calming pattern."

"Bedtime has shifted later this week, but nighttime stretches between feeds are getting longer."

Nap Timing Help

See when the next nap is likely coming based on your baby's recent rhythm instead of relying on generic charts.

Next Nap: ~2:15 PM (1:50 - 2:40 PM window)
Wake Window: Awake for 2h 10m - based on your baby's pattern
Bedtime Forecast: Tonight looks easier than average

Weekly Summaries

Review the week quickly with a clear summary of sleep and feeding trends without digging through the full timeline.

This Week: Ellie averaged 8 feeds/day, up from 7 last week
Sleep Trend: Night stretches growing - 4.2h avg vs 3.5h last week
Heads Up: At 6 weeks, expect evening cluster feeding to increase

Ask LunaAI

Ask clear questions about your baby's recent data and get answers grounded in what you have actually logged.

Is my baby getting enough sleep?
Based on the last 7 days, Ellie is averaging 14.2 hours of total sleep, which is right on track for 3 months. Her longest stretch was 5h 20m last night.
Try asking: "Are naps improving?" "Is bedtime too late?" "How much did she eat today?"
