Description
This is a fun and scientifically based way to predict when your baby (or babies!) will actually be born.
Does it work?
So far in our initial analysis, Baby Birthday was 58% accurate at predicting the exact date of delivery. This was 11 times better than the due date itself (which is correct only 4-5% of the time).
Baby Birthday outperformed the due date in predicting delivery day 83% of the time!
"...You’ll also be provided with percentages for how likely you are to deliver in the next day, next three days, week, two weeks, month or next two months. These percentages will become more accurate as you approach your due date.
Baby Birthday is the first due date calculator I’ve tried that takes all of these factors into account. I think it’s terrific that there’s now a more personalized alternative..."

The due date you get at your prenatal visit is just an estimate. In fact, only 5% of mothers give birth on the due date, which is just the date that your baby will be 40 weeks along in development. Lots of things affect the actual date of your baby’s birth.
This is not just a due date calculator. Developed by an experienced obstetrician, Baby Birthday is something completely new and different:
Baby Birthday predicts your baby’s actual birthday and the chance the baby will be born in a certain time window – for instance, will your baby be born before your mother-in-law arrives to help at home?
Many factors determine when you will deliver, including when you go into labor, when your water breaks, or when you might need to be delivered for some other reason to reduce the risk of complications.
The Baby Birthday formula takes into account many factors including:
•Your prior birth history
•Your individual medical and surgical history
•Your physical exam findings
…and, using the Core Location abilities of your iPhone,
•the barometric pressure patterns that can sometimes affect your pregnancy!
Many other factors are also used to calculate your prediction, including how far along you are (for example, the further along you get, the more likely you are to keep going past the due date!) and even logistics like the day of the week.
As an obstetrician, the question I am asked most is, “When will my baby be born?”.
Finally, Baby Birthday helps answer that question.
I hope you will have fun learning about the many factors that influence your baby’s birth date, while waiting for that special day to arrive!
Also: in the lower right corner of every page, you will see an info icon. Tap that to learn more about each topic. You’ll find detailed information about the effect of medical and surgical history on your pregnancy, packing lists, information about your cervical exam, and more!
Baby Birthday offers a lot of useful information even early in pregnancy, but it is really exciting in that last trimester, when your predictions will change every day! Come back daily in the third trimester to keep track of your special package delivery date!
Of course, always consult your own doctor or prenatal care provider for advice about your individual medical circumstances.
Congratulations and best wishes for you and your baby!

A fun and useful app for moms-to-be
As a nurse practitioner delivering prenatal care for over 15 years, I am frequently asked by my patients if they are likely to deliver early or late, etc. Sometimes they need to plan care for their other children, or know when their Mom should buy her airline ticket to come and be with her at the birth. This app is a fun (and useful) tool to give a mom-to-be some factors to consider, and some prediction beyond a general "only your baby knows" response!
Of course, every woman's pregnancy differs, and no single prediction algorithm can cover all the factors, but Baby BIrthday provides a thoughtful way to help my patients understand the many variables that go into the answer to their question.
A sophisticated "baby birthday" calculator
Update (12/272010):
It's very nice to see the developer continuing to refine the app and respond to questions and suggestions from users.
Original Review (12/1/2010):
This clever app by an OB leads you through a series of questions to compute when your baby (or babies!) is likely to be born. The app's calculation includes the usual variables (e.g., lengths of prior pregnancies) and some surprising, at least to me, variables (such as the barometric pressure). The result of the calculation is not just a forecast for a particular birthday but a set of probabilities that your baby will be born in the next day, next week, next month, etc.
The app includes many (iPhone) pages of well-written descriptions of all the inputs into the calculation and lots of additional information, too. I haven't encountered any bugs.
I highly recommend Baby Birthday!
