I downloaded it the other day. It's called iPregnancy. It's got a couple of cool features. You can even put in your next doctor's appt. and it will give you a reminder every time you open the app. It costs $2.99 (and keeps me entertained during my commute Chat Icon). Here is some info I found online regarding the app:

• Current gestational age in weeks and days (like doctors use)

• Current gestational age in lunar months

• Progress bar that will show you how far you have progressed

• Current Trimester

• Time remaining until your due date (in weeks and days)

• Time remaining until your next milestone (in weeks and days)

• Time mode selectable in either days or weeks/days


This program features a beautiful interface with background that changes depending on the selected gender of your baby and also includes the following key features:

• A 3-D ultrasound picture of the baby at each week!

• Baby Information including a brief summary of happenings with the baby at the current gestational age as well as information about the average length and weight of the baby.

• A baby name picker which allows you to keep a list of baby name contenders. This picker derives names from the Social Security Administration’s top 1000 names for last year. These are sortable alphabetically or by relative popularity. You also have the option of entering custom names.
