Cycle Length Adjustment
Personalize calculations for irregular cycles (21-35 days) to improve due date accuracy.
Gestational Age Tracking
Real-time calculation of current pregnancy week and day, with automatic daily updates.
Trimester Identification
Automatic identification of current trimester with phase-specific information and guidance.
Multiple Pregnancy Support
Adjusted calculations for twins, triplets, and higher-order multiples with earlier expected delivery dates.
