DueDateCalc is a fully-functional Obstetric calculator designed to calculate due dates and current gestational age. This program is written by a practicing OB!

Using DueDateCalc, you will be able to calculate due dates and current Gestational Age based on Last Menstrual Period, Conception Date, UltraSound Date/Gestational Age, and Estimated Date of Confinement.

*** THIS CALCULATOR ACCOUNTS FOR LEAP YEARS (unlike some other due date calculators) ***

You also get the ability to play "what if" by changing the "As of Date" back or forward as well as the ability to back-calculate the other key dates by "Locking EDC".

Finally, an Estimated Fetal Weight table is included so you can see EFWs in grams or pounds/ounces based on current gestational age.

This has everything a practicing OB could need in a Due Date Calculator!

If you would like the ability to track ALL of your OB patients, see my other program: OB Patient Tracker, also available on the iTunes App Store!!

Pros and cons of Due Date Calc OB app for iPhone and iPad

Due Date Calc OB app good for

This calculator allows you to Gestation for a future date Which is great for prepping charts for future clinic.
Wow! This works extremely well! I really appreciate it. Thanks so much for a well designed app that works perfectly.
Works well, easy to use. Nice to calculate due dates for friends, family, etc - cant wait to get the patient tracker to have all the info on my patients handy!
Intuitive for ease of use. Calculate EDD from LMP or Ultrasound.
Love this app. I had been unimpressed with the other due date calcs and was beginning to think I wouldnt find one Id be satisfied with. It has all the features I need and it takes into account leap years, too (unlike some of the others).
I am a practicing OB/Gyn, and Ive been using this for about two months. It is obvious that the author is an OB. He ha figured out how to duplicate all of the functions of the venerable wheel, in a fairly intuitive interface. As someone who is very particular about interfaces, I would rate this programs interface as a solid 4 on a 5 point scale.

Some bad moments

I have been in OB/GYN for 20 years, and having been using PRegCalc Pro for palm to track my ob patients. Would LOVE to see this for iTouch. DueDate Calc is a great piece of software. But an app that can track current patients is definitely needed!
