Baby Tracking & Parenting Companion
Track feeding, sleep, diapers, and milestones. WHO growth charts, voice logging, and collaborative caregiving with real-time family sync.




Parenting data is scattered everywhere — feeding logs in one app, sleep schedules in another, growth measurements on paper, photos buried in camera rolls. When multiple caregivers are involved (grandparents, nannies, co-parents), nobody has the full picture.
Koo is a single hub for everything. Log activities by voice or tap, track growth against WHO percentile curves (0–24 months, gender-specific), and share milestones through a private Village feed visible only to invited family. Each caregiver gets role-based access — admins manage everything, caretakers log activities, family members see milestones, consultants get read-only data views.
It works offline first. Activities are cached locally and sync via Supabase Realtime when connected. Grounded in WHO, AAP, and CDC guidelines — not internet parenting advice.
Say "4 oz bottle" and the form auto-fills. Natural speech recognition transforms words into structured activity data.
Clinical-grade percentile tracking (3rd–97th) for weight and length, 0–24 months, gender-specific.
Share milestones privately with invited family. Reactions, celebrations, and confetti — no public exposure.
Invite caregivers with role-based access. Admin, caretaker, family, and consultant roles with different permissions.
