Luni - Swiss Baby Tracker &Log

Your baby's data belongs to you — and only you.

Luni stores everything on your device and in your personal iCloud. No account. No server. No analytics. No one else ever sees your baby's data. Not even us.

YOUR DATA, YOUR DEVICE Unlike other baby trackers, Luni never uploads your data to external servers. Every feeding, every nap, every diaper change stays in your own iCloud — encrypted by Apple, controlled by you. No account to create, no terms to accept, no data to worry about.

SHARE WITH UNLIMITED CAREGIVERS Send one link to your partner, grandma, nanny, or anyone who helps. They see the same timeline in real time via iCloud — across different Apple IDs. Every event shows who logged it. Add as many caregivers as you need.

TRACK EVERYTHING WITH ONE HAND

• Feeding: breast (left/right/both), bottle, formula with live timer
• Sleep: nap and night sleep with one-tap start/stop
• Diapers: contents, color, and consistency
• Growth: weight, height, head circumference with WHO percentile charts and growth projection

SMART INSIGHTS

• Sleep: longest stretch, bedtime consistency, wake windows, day/night ratio
• Feeding: average feeds per day, duration, gaps between feeds
• Diaper: daily counts, color trends, type breakdown
• Growth: WHO percentile curves with projected growth trajectory

SWISS BABY REMINDERS (PRO) Never miss a check-up, vaccination, or deadline. Luni includes reminders for the things Swiss parents need to do — from pediatrician visits and BAG vaccinations to insurance applications and birth registration. Based on official Swiss recommendations. For informational purposes — not medical advice.

PERSONALIZED SLEEP PREDICTIONS (PRO) Our Bayesian engine learns your baby's unique sleep rhythm and predicts when the next nap is due — with confidence windows that improve over time.

APPLE WATCH (PRO) Start and stop timers from your wrist when both hands are full. Log past events with the crown time picker. Complications show your running timer and next predicted nap window right on your watch face.
