## What is 9 Months?

9 Months is a due-date and ovulation calculator — not a tracker. Enter the first day of your last period and get an estimated due date, a week-by-week pregnancy timeline, and your fertile window.

No account. No cycle log. Nothing leaves your phone.

WHAT IT DOES
• Due date from last period, conception date, IVF transfer (day 3 or day 5), or an ultrasound measurement
• Current gestational age in weeks and days, with trimester start and end dates
• A full week-by-week timeline to 40 weeks
• Key dates: end of first trimester, viability, full term, due date
• A real month calendar — fertile window and predicted ovulation, or due date and trimester milestones
• Ovulation mode: fertile window, predicted ovulation day, and next expected period from your cycle

9 MONTHS PRO
The calendar view, ovulation mode, IVF and ultrasound dating methods, and multiple saved dates are part of Pro — a one-time purchase, yours for good. The core due-date calculator from last period is free and stays free.

PRIVACY, ACTUALLY
Most pregnancy and ovulation apps want an account, a cycle log, and your data on their servers. This one asks for one date and keeps it on your device. There is no sign-up, no analytics, and no network calls at all — the only outside connection is Apple's App Store for the one-time Pro purchase.

Every number shown is an estimate based on standard obstetric formulas. This app does not diagnose pregnancy and is not a substitute for medical advice — talk to a healthcare provider about your care.
