Many of us in Family Medicine practice full scope including obstetrics. This is one of the most rewarding aspects of the specialty, but also one of the most challenging with very unpredictable hours and significant medical legal risk. Many other providers in primary care and OB/GYN may only provide outpatient prenatal care which is equally rewarding with a somewhat more predictable lifestyle. Regardless of what scope of obstetrics care you provide, a good OB wheel app is a must.

With so many different OB wheel apps available, which one should we use? Previously on iMedicalApps we have reviewed a number of the currently available OB wheel apps including what we felt were the best available for iOS and Android.

I recently reviewed Dr Joshua Steinberg’s latest, OB Wheels, which I thought was perhaps a bit too ambitious, but very complete. We also have reviewed the free Ferring IVF Wheel and OB App Suite. We even tried out an Apple Watch OB wheel app, but felt it was just too tedious to use.

My favorite remains the easy to use, OB Wheel, an excellent medical app designed to assist providers in dating pregnancies and adjusting for sonographic data. The latest entry to the OB wheel universe comes from the American Congress of Obstetricians and Gynecologists (ACOG). They have updated their popular and well-reviewed ACOG App to include a new pregnancy calculator.

The ACOG Pregnancy App consists of simple blue rectangles that calculate the Estimated Date of Delivery (EDD) based on various data: a calculator based on Last Menstrual Period (LMP) and ultrasonography, LMP alone, ultrasound alone, gestational age and Artificial Reproductive Techniques (ART). This is one of the only calculators available that includes ART along with more standard calculations. The medical app uses the guidance from the 2014 ACOG Bulletin on dating pregnancies which is included in the app. This gives the obstetrics provider all the tools they need to date, track, adjust delivery dates, etc.

Clinical Scenario

You are seeing your new continuity obstetric patient today. The pregnancy appears uncomplicated based on prenatal labs and maternal history, but the patient is not entirely sure of her LMP. Your colleague performed a first trimester ultrasound a week ago that is shows a difference of 10 days between the ultrasound and LMP dates for the patient’s EDD. Which do you use? The ACOG Pregnancy App will help you with this decision! Let’s take a look at OB Wheels in action.

Evidence based medicine

The new ACOG Pregnancy App incorporates the most current ACOG guideline and previously accepted standards for dating pregnancies. Most importantly, the app contains information to help adjust dating based on sonographic data and artificial reproductive techniques.

What providers would benefit from this App?

Students, residents, mid-levels, Family Medicine, Midwives, OB/GYN and any provider who performs obstetrics.

  • Price
    • Free
    • Contains the current ACOG dating bulletin data.
    • Multiple methods of dating included, even EDD based on ART and target dates.
    • Automatically changes dates based on sonographic data.
  • Dislikes
    • Medical app is within the larger ACOG app; would be nice if available separately.
    • Initial calculation assumes you have both the LMP and US date.
    • No patient tracking capabilities.
    • No data beyond just the “facts” of the calculated date such trimester dates.
  • Overall

    A nice new entry to the OB Wheel universe. The ACOG OB/GYN medical app makes their existing app that much more necessary to obstetric providers who may still be using their plastic wheels.  As a plus, the medical app is one of the only OB Wheel apps to include EDD based on ART.

  • Overall Score
  • User Interface

    Easy to use even though it is a section of larger medical app. The obgyn medical app includes multiple ways to calculate EDD.

  • Multimedia Usage

    No real multimedia capabilities, but unnecessary in this type of app. No patient tracker function.

  • Price

    App is free!

  • Real World Applicability

    An already useful app now has a practical capability with some new tricks. Still may not replace my “old reliable” OB Wheel App for sheer simplicity and convenience.
