ParentSync Planner is a playful way for couples to explore the classic question: boy or girl?
Enter the birth month and year of both partners and ParentSync Planner compares popular prediction methods side by side, month by month. See where the methods agree, then share a result card with family and friends.
HOW IT WORKS
• Planning mode: pick a reference year and browse the months where the methods point to a boy or a girl.
• Pregnant mode: enter the first day of your last period to get an estimated due date and see what each method says for that month.
• Method match: ParentSync cycles and the Chinese lunar chart, plus the Mayan method with Premium, with a simple "X of Y methods agree" summary.
• Share card: create an image with your result and share it through your phone's share sheet.

JUST FOR FUN
ParentSync Planner is for entertainment and informational purposes only. The Chinese lunar chart and the Mayan method are popular traditions, not science. The app cannot predict or influence the sex of a baby and is not a medical, fertility, pregnancy or contraception tool. Talk to a healthcare professional for medical advice.
