PregTrack

PregTrack is built on the clinically accepted Naegele's Rule (LMP + 280 days) to deliver accurate, week-by-week pregnancy data management. PROFESSIONAL DATA COVERAGE • Dual Input Modes: Enter your due date directly, or calculate from your Last Menstrual Period (LMP) — the system automatically resolves the correct dates. • Complete 40-Week Dataset: Fetal developmental milestones, length (cm), and weight (g) with medically referenced values across all 40 weeks. • Trimester Segmentation: First, second, and third trimester clearly labeled with key clinical checkpoints visualized. • Prenatal Checklists: 3–5 medically-informed tasks per week — prenatal visits, supplement schedules, screening tests — tracked with persistent checkboxes. DATA PRIVACY All data is persisted locally using Apple's SwiftData framework. Zero server uploads. Fully compliant with health app privacy best practices. SYSTEM REQUIREMENTS iOS 17.0+, iPhone. Interface language automatically follows your system locale (English / Simplified Chinese).
