Evelyn: Baby Tracker & Growth

Welcome to the most important journey of your life — parenthood.

Evelyn - Baby Tracker is your calm, science-backed companion for understanding every step of your baby's development from day one. Built for parents who want clarity without clutter, Evelyn combines Wonder Weeks developmental leap tracking with a complete suite of health and milestone tools — all stored privately on your device.

🌟 KEY FEATURES

⚡ Wonder Weeks — Developmental Leaps
Understand why your baby is suddenly fussy, clingy, or not sleeping. Evelyn maps your baby's developmental leaps (stormy periods) and sunny windows onto a personal calendar so you're always one step ahead.

🍼 Feeding Tracker
Log breastfeeding sessions, formula feeds, and solid meals. Daily charts show feeding volume trends so you can spot patterns and adjust your baby's nutrition with confidence.

🦷 Teething Journal
Track all 20 primary teeth as they emerge. Record the exact date each tooth appears and keep a complete teething history at your fingertips.

📈 Growth Charts — WHO Standards
Log weight, height, and head circumference. Evelyn plots your baby's measurements directly against World Health Organization (WHO) growth reference curves so you can see at a glance whether your baby is on track.

🏅 Developmental Milestones
A curated checklist of motor, cognitive, language, and social milestones. Capture the exact date your baby first smiled, rolled over, or said their first word — memories you'll treasure forever.

⏰ Smart Reminders
Set reminders for feeding times, vaccination appointments, check-ups, or any custom event. Flexible scheduling means you'll never miss an important moment.

👶 Multiple Baby Profiles
Managing more than one child? Evelyn supports multiple baby profiles in a single app — switch between them instantly.

👨‍👩‍👧 Family Sharing (Optional)
Invite your partner with a 72-hour code and sync baby data securely across devices in real time. Sign in with Google to get started — or keep using Evelyn fully offline without an account; the choice is always yours.

📋 Daily Checklists
Pack the diaper bag once, reuse it forever. 10 smart templates (diaper bag, bedtime, bath time, doctor visits, beach day, travel, and more) automatically update as your baby grows from newborn to toddler.

🛡️ PRIVACY & SECURITY

Your baby's data is precious. Evelyn is built with privacy as a first principle:

• Offline-First — all core features work without an account or internet connection.
• Optional Sign-In — Google Sign-In only if you choose to use Family Sharing.
• Your Family, Your Data — only your family's shared data syncs; nothing else leaves your device.
• No Ads, No Tracking — your family's moments are never monetised.
• Leave Anytime — you can leave your family group and delete all cloud data at any time.

Parenthood is hard enough. Evelyn keeps things simple, private, and focused on what matters most — your baby.

Evelyn — Your baby's first chapter.
