Stop the anxiety, understand your baby's growth with science! DaMilestone is a professional development monitoring app designed for families with children aged 0-6. We combine authoritative Chinese assessment scales with US CDC standards, helping you complete medical-grade developmental assessments at home. # Why Choose DaMilestone? - Dual Authority Standards: Go beyond a single metric! We integrate China's comprehensive developmental assessment system (covering gross motor, fine motor, language, adaptive, and personal-social domains) with US CDC milestones. East meets West for a more objective, international perspective on your child's development. - Privacy-First: We're committed to zero data collection. Whether assessment results or baby's information, all calculations run locally on your device—offline. We don't upload or track your parenting data. - Visual Insights: Automatically calculate Developmental Quotient (DQ) and Developmental Age (DA), displayed through intuitive radar charts. See strengths and areas for support at a glance, making early education more targeted. - Easy to Use, Professional Guidance: No medical background needed. Each assessment item includes detailed visual guides and criteria. From rolling over to first words, parents can confidently complete professional observations at home. # From the Developer Hi! I'm the indie developer behind this app, and also a father of a 2-year-old. I built this tool because I've experienced the confusion and anxiety of parenting firsthand. Every assessment criterion here has been thoroughly verified. I hope this isn't just a cold tracking tool, but a warm companion that reduces fragmentation and anxiety in your parenting journey. If you have any questions, join our parent community to chat directly with me, discuss assessment logic, and share parenting experiences. # Disclaimer Assessment results provided by this app are for home monitoring and parenting reference only. Affected by home environment and subjective factors, results do not constitute clinical diagnosis. If you notice significant developmental delays or have concerns, please consult a licensed pediatrician.
