Partus: Pregnancy Wheel

The OB wheel that respects your time — and your privacy. Free to download: one screen with every date, the reverse week calculator and reference biometry. A single one-time unlock adds ACOG ultrasound redating, IVF transfer dating and the Bishop score. No account, no subscription, no data collected. WHEEL (free) — one screen with every date: LMP, conception, gestational age today and due date. Tap any element to edit; everything recalculates instantly, in both directions. WEEKS (free) — the reverse calculator: "the patient was 12 w 0 d on…" reconstructs LMP and EDD. Plus trimester ends and week-by-week date ranges with reference biometry. PARTUS PRO — one purchase, yours forever, no subscription: - ULTRASOUND REDATING (ACOG) — enter the exam date and the measured gestational age; Partus applies the ACOG Committee Opinion 700 thresholds (reaffirmed 2025) and tells you plainly which dating applies and why. - IVF DATING — day-3, day-5 or day-6 transfer date gives the EDD with no LMP at all, fresh or frozen (FET). The wheel keeps a visible note that dates came from IVF. - BISHOP SCORE — five parameters, instant score and interpretation: 6 or less unfavorable, 7 intermediate, 8 or more favorable. PRIVATE BY DESIGN — works fully offline and collects nothing. No account, no ads, no data collected. FREE WEB CALCULATORS — pregnancy wheel, ACOG redating, IVF due date and Bishop score: partuswheel.app Partus is a reference calculator for healthcare professionals. It does not provide medical advice or diagnosis.
