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 ASCCP Risk-Based Management Consensus Guidelines provide evidence-based recommendations for managing abnormal cervical cancer screening results and cancer precursors, including post-colposcopy and post-treatment scenarios. ASCCP is pleased to offer this app to streamline navigation of the ASCCP Risk-Based Management Consensus Guidelines for abnormal cervical cancer screening tests and cancer precursors. The guidelines articles, as published in the Journal of Lower Genital Tract Disease, as well as the comprehensive risk estimates, can be accessed through https://www.asccp.org/guidelines. These evidence-based management guidelines, initially developed in 2019, came together through a consensus process of 19 organizations. The updated management guidelines aim to: • Allow for a more complete and precise estimation of risk • Provide more appropriate intervention for high-risk individuals (detect and treat more precancer) • Recommend less intervention for low-risk individuals (decrease testing and treatment that won’t prevent cancer and may cause reproductive harm) • Allow for the future addition of new risk modifiers and screening and management technologies See https://www.asccp.org/UserGuide for tips on using the app.

Verdict
The clearest difference is price: OB Wheels at Free against ASCCP Management Guidelines's $14.99. OB Wheels also leads on iOS requirement (7.0 vs 11.2). ASCCP Management Guidelines's advantage is rating (4.8 vs 2.3) and update cadence (every 3 months vs every 18 months). On ads, in-app purchases, monetization model and device support there is nothing between them.
