Initial figures have been released demonstrating the ability of the Baby Birthday iPhone app to accurately predict when an expectant mother will deliver. Babies are rarely born on their due date. Baby Birthday for the iPhone predicts the real delivery date based on the mother’s medical history, exam, and progress through pregnancy. Results? 58% of mothers deliver on the predicted date! This is 11 times more accurate than the due date alone. This app outperforms the due date 83% of the time.
