2. OB Wheels

Download the App on the Apple Store by clicking this Button
“Does the world need another OB-wheel-due-date-calculator app? You bet! OB Wheels combines three things that clinicians need to derive all the dates necessary in pregnancy care, and no other app has this combination.

It contains a calendar calculator to determine EDD (EDC) from LMP or from a sonogram report. The calendar calculator also provides gestational age (EGA) as of any date for a given EDD or LMP. Because the calculator works off the real calendar, it is accurate for leap years too.

Then for all of you who miss your cardboard OB wheel, the app contains one which you can rotate, pinch and zoom, and generally play with just like a regular cardboard wheel. It’s a little tricky to learn how to plant two fingers and rotate them rather than pinch-and-zoom to get rotation versus resizing. But the wheel works and it is accurate, especially so because you can zoom in to be sure where the little date hash lines lie.

Finally, the app notes the most recent committee opinion scheme from ACOG on how one might reconcile due dates from LMP and sonograms to arrive at a single final EDD. To my knowledge, the scheme is authority-based and no better or worse than other schemes, but my practice and my learners need a single clear scheme, so this app includes one for easy reference.

As an educator and clinician myself, I am grateful for feedback. Email me via the contact email at my website.”

“The OB Wheel Pro 7 is the most complete, powerful, and easiest-to-use tool for healthcare professionals providing prenatal care. In just ONE app there is 1) a gestational age calculator, 2) an ultrasound biometric calculator, 3) a fetal weight calculator, 4) a list of key weeks and trimesters, 5) an age-adjusted risk table for trisomy 21 and aneuploidy, 6) a BMI calculator, and NOW 7) an Apple Watch app is included with your purchase!

The OB Wheel Pro 7 is a state-of-the-art gestational age calculator (also known as an obstetric or pregnancy wheel) that is used every day by doctors, obstetricians, midwives, nurses, and pregnant women. The OB Wheel Pro 7 is a professional tool that replaces the need for multiple apps and it greatly enhances the functionality of those worn-out cardboard wheels without compromise.

The OB Wheel Pro 7 accurately determines the estimated delivery date (EDD), or due date, of a pregnancy based on the first day of a woman’s last menstrual period (LMP), or from the date of conception, or from a known gestational age (GA) on a known date, e.g. from an ultrasound measurement, or from fetal biometry like Crown-Rump Length (CRL), Femur Length (FL), and BiParietal Diameter (BPD). Additionally, for appropriate gestational ages, The The OB Wheel Pro 7 estimates fetal weight and displays the number of days completed and remaining.

The OB Wheel Pro 7, besides calculating GA from fetal ultrasound biometrics, enables clinicians to also calculate Estimated Fetal Weight (EFW) from FL, BPD, Head Circumference (HC), and Abdominal Circumference (AC) using the most appropriate published reference formula using the maximum and most appropriate parameters.

Prenatal care providers know that there are key gestational ages where testing or interventions are needed. The OB Wheel Pro 7 lets providers see at a glance when these items should be scheduled.

• Includes Apple Watch app!
• Gestational Age Calculator from LMP, EDD, Conception Date for any reference date
