Safe Days provides a user-friendly calendar-style interface that accurately predicts ovulation days, fertile days, infertile days, and even the chances of conceiving a baby boy or girl. The application's main goal is to empower women with knowledge about their reproductive health, allowing them to make informed decisions regarding family planning. By simply inputting the start and end dates of their menstrual cycles, users can access a comprehensive overview of their fertility status for each day.
