Nivellia is the digital companion for your family, from pregnancy through baby's early years — a complete personal journal, built to be shared between two parents.

🤰 PREGNANCY JOURNAL
Follow baby's progress week by week, prepare your hospital bag with a customizable checklist, and get a nutrition tip tailored to each stage.

📒 PERSONAL HEALTH JOURNAL

Growth charts (weight, height, head circumference) with official reference standards
Vaccination schedule reference based on your country (12 countries covered)
Personal notes with photos, plus a contacts and appointments organizer
PDF export of your journal, handy to bring along to appointments

😴 SLEEP, BREASTFEEDING & BOTTLE
A timer for naps, nights, breastfeeding, and bottles — with detailed history and flexible manual entry if you forget to start the timer.

🧠 INTELLIGENCE, CALCULATED LOCALLY
Nivellia estimates baby's next feeding time, calculates their growth trend, and highlights upcoming vaccination reminders — every calculation happens right on your phone, never on an external server.

👨‍👩‍👧 TOGETHER, AS A FAMILY
An invite code links both parents to the same journal, synced in real time. Assign a task to your partner and get notified once it's done.

💕 MOMENTS TO SHARE

The Name Match: swipe separately and discover the names you both loved, from over 400 options
Milestone Cards: capture every big first in a beautiful card, ready to share
Task Coin Flip: let fate settle who's doing the chore
White Noise: three soothing sounds to help baby fall asleep

✈️ ALWAYS AVAILABLE
Full offline mode, multi-language, accessible (colorblind mode, larger text) — your data stays accessible even without a connection.

🔒 YOUR DATA STAYS YOURS
No data selling, no ads. Your personal information stays private to your family.

This app is not a medical device and does not diagnose, treat, or prevent any condition. Always consult a qualified healthcare professional for medical advice.

Nivellia is free to discover the essentials: full pregnancy tracking, one child profile, and the core features of the journal. Nivellia + unlocks everything else for the whole family — unlimited children, full growth charts, PDF export, and more — with a single subscription that covers both parents.
