BabyNook — Baby Development Tracker & Parenting App
A privacy-first, all-in-one baby development tracker and parenting app. Parents log growth and milestones against CDC and WHO benchmarks, discover 216 age-perfect activities, and share every first with family — all backed by Alex, an AI companion tuned to their baby's exact age.
Key Features
- Track & Log: 131 CDC milestone benchmarks across 11 areas, plus WHO growth percentiles, teeth, sleep, and nutrition — with typical ranges instead of pressure.
- Play & Activities: 216 curated activities — sensory play, lullabies, music discovery, books, and family excursions linked to skill development.
- Share & Connect: Invite family with a single link — comments, reactions, and end-to-end encrypted photos, without social media.
Business Value
"Built as a privacy-first alternative to ad-driven baby trackers — end-to-end encrypted by design, GDPR-compliant from day one, with no ads and no data selling."
