LunaLog is the calm baby tracker that learns your baby's rhythm — feeds, naps, and diapers in one shared place, the next nap predicted, and every caregiver on the same page.
Everyday tracking is free. No card required. Also on the App Store and Google Play.
Somewhere around week three, the days blur. Was that feed at 2 or 3? Is she due for a nap — or already overdue? LunaLog replaces the 3 AM mental math with one calm place that keeps track for you.
Log the nap in two taps — LunaLog already knew it was coming.
Name and birthday — that's it. LunaLog starts with age-based sleep rhythms from day one, then tunes them to your baby.
Feeds, naps, and diapers in a couple of taps — fast enough for one hand in a dark nursery.
Your partner, grandma, the sitter. Everyone sees the same live day on their own phone — or in a browser, no install needed.
After a few days of logging, LunaLog learns your baby's personal rhythm and predicts the next nap window — from your baby's own patterns, not a generic chart. Then it turns the whole day into a plan you can actually follow.
Everyone caring for your baby shares one live timeline. Log a feed and your partner's phone shows it seconds later — handoffs stop being an interview, and the 3 AM shift knows exactly where the day left off.
Everything you need to track the day and stay in sync is free — for as many caregivers as you have.
