## What is WeightAtBirth?

Are you pregnant and want to check your baby's birth weight? WeightAtBirth uses two distinct methods to predict your baby's weight at birth. The app's prediction methods are based on published scientific/medical research - references included in the app. The first method, uses simple maternal height and weight measurements during pregnancy, and allows to predict the baby's weight at birth, any time after pregnancy week 37. The second method combines simple measurements with ultrasound measurements of the fetal weight and allows to obtain predictions starting with pregnancy week 28.

Besides the prediction of the baby's birth weight the app issues the estimated percentile for the baby's birth weight. Weight percentiles give you an indication of how does your baby's birth weight compare with other birth weights for similar maternal, and pregnancy conditions. 

DISCLAIMER: Regardless of the information you obtain from this app, you are urged to seek OBGYN advice during your whole pregnancy.

### 5/5 — This app is awesome

*2015-06-09, version 1.2*

Just had my baby and estimates were so close it's crazy. The app was off by an Oz I would say that is pretty good for predictions. Not only that it guessed better than the ultrasound did. Ultrasound was off by pounds.

### 1/5 — Scam

*2015-04-11, version 1.1*

Paid for app and does not work.
