OB Wheels vs BiliBuddy

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.

BiliBuddy supports clinicians assessing neonatal jaundice in infants born at 35 weeks of gestation or later. Use Quick Check to compare a total serum bilirubin reading with American Academy of Pediatrics (AAP) 2022 phototherapy, escalation-of-care, and exchange-transfusion thresholds. Enter age in hours, gestation, and additional neurotoxicity risk factors. View the result and threshold charts in mg/dL or µmol/L. Track infants locally to review reading history, plot trends, and calculate the rate of rise. A date-and-time calculator helps determine age at measurement. Share a text result summary using the device's share sheet. The 2022 guideline is selected by default. An optional legacy AAP 2004 pathway is available in Settings, with its supported chart range clearly identified. Reference material and links to source guidelines are included. Clinical entries are stored on the device. Usage analytics is optional and off by default. Advertising and crash diagnostics use third-party services described in the in-app Privacy Notice. An in-app purchase removes ads, and Restore Purchases restores an eligible prior purchase. For clinician use. BiliBuddy does not replace clinical judgment, clinical assessment, or consultation of the source guideline. It is not an electronic health record. Do not use outside the supported age and gestation ranges.
