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.

Cumbersome

Wheel is cumbersome and hard to use. Too much screen manipulation required to make it easy to use. Still....it’s worth the price.
Works great

I don’t understand all the negative reviews. You put in the LMP or the ultrasound Dating and it tells you what you need to know. Simple as that. Tells you when to use U/S vs LMP also. The “wheel” is clunky and kind of pointless if you ask me. I always just use the calendar based calculator.
Difficult to manipulate wheel

Don’t bother with this one, it’s too hard to move the wheel. Plus, there is no spot for LMP on the outer wheel.

In your last update Mar 8 2016 this app never installed after many trials. Will you find solution to this problem Thanks
Difficult to use

OB nurse for 20 years. Enjoy the online calculators rather than looking at a wheel. Neither of the applications within the app were easy to use to find the gestational age. I went looking for another.

Not intuitive at all. I’d use a cardboard wheel over this, even in the dark. Two thumbs down.
It IS tricky to use, but it DOES work

So, the app has two functions. One is the Calendar Based Calculator and the other is the Traditional OB Wheel. The OB Wheel is REALLY tricky to use (the app says it so itself in the Wheel window) and does take a lot of practice to get the grip of it, but does work like any other cardboard wheel. The calculator is digital, so I don’t understand how anyone can have problem using it or find it complicated, except that don’t know how to properly use their phone and/or have little fine touch skills. To the developers, thanks for making this nice app and leaving it free of cost. As a suggestion, maybe if it were compatible with iPad it would be easier for more users to be able to work with the Traditional OB Wheel, as the screen of an iPhone is kinda small (even in the iPhone Plus) to maneuver it. Nevertheless, very helpful.
