The Marble app is a novel tool for new parents to use to track their baby’s development in-between doctor visits. The app gives parents of newborn infants many advantages, including: - Tracking for feedings, sleeping, diapers, and growth across all developmental milestones: physical, gross motor, communication, cognitive, social, and emotional. - Easy sharing of reports with statistical data and patterns about an infant with a doctor to review and analyze health and developmental information. - Multiple caregivers (including parents, grandparents, nannies, and members of the extended families) can stay updated regarding an infant’s development and growth. They can assist with tracking by adding data and adding pictures directly to the app. - Library with medically backed articles and activities to provide valuable content to parents. - Photo timelines categorized by milestones and age to have all of the infant’s photos in one place that is easily accessible by all caregivers within the app. - Multiple profiles can be created for each infant to the same app for parents with more than one child. Using AI – Marble will bring customized insights and personalized resources tailored to your baby.
