The first wearable designed to track your baby's development — starting with sleep and language — built for real-time check-ins today and long-term insight as your child grows.
The words your baby hears — and the back-and-forth exchanges they have — in their first year are the foundation for language, cognition, and connection. Doozy's language environment monitoring is backed by decades of research in developmental science. It counts every word, every conversation, every moment that matters.
Doozy distinguishes live human speech from TV and background noise — because only real voices build vocabulary.
Serve-and-return conversations — where caregiver and baby respond to each other — are the most powerful input for language development.
From first protowords to true first words, Doozy tracks your baby's vocal output over time and celebrates every step forward.
Most baby sleep trackers only know what's happening when your baby is in bed, or rely on you remembering to log naps. Doozy tracks sleep state, activity, and drowsiness throughout the entire day — at home, at daycare, in the stroller — wherever your baby actually is.
Know whether your baby is truly asleep, in restful wake, or getting drowsy — without lifting a finger or opening the door.
Get notified before the optimal nap window opens so you can set the scene — not scramble when they're already overtired.
Doozy learns your baby's individual patterns and explains what's changing — nap consolidation, sleep regressions, night wakings — in plain language.
Continuous passive monitoring creates a data foundation that will unlock the future of infant healthcare.
Real-time sleep state, predictive nap windows, language-rich day scoring, conversation counts, and an AI sleep consultant personalised to your baby's age and patterns.
With enough longitudinal data, Doozy will be able to flag patterns that may indicate developmental differences — giving families a head start before formal assessment.
Continuous, objective at-home data collection for clinical trials — no more sparse clinic visits. Doozy creates a continuous vital record that researchers can actually rely on.
Heart rate, respiratory patterns, movement, and sound — passively, 24/7. The foundation for AI-powered infant healthcare that doesn't require a hospital visit.
Share a week of verified vital data with your pediatrician before every visit, and let AI flag what needs attention — turning routine check-ins into truly informed conversations.
Every Doozy creates anonymised, longitudinal data. The more babies in the network, the better the models get — for every family, not just the ones in a clinic.
Doozy is a feather-light fabric band designed to be worn all day, every day — from newborn through toddlerhood. No rigid plastics, no harsh edges, no charging every night.
