Simple, fast, yet more thorough than any other pregnancy wheel available for the iPhone, Perfect OB Wheel is better than just a replacement for your trusty paper wheel.

You enter the last menstrual period (LMP) date, conception date, estimated date of delivery (EDC), or number of weeks at a given date. You can use the numeric entry pad (0 3 3 0 2 0 0 8) and immediately see the results, or you can spin the date wheel at the bottom of the screen and tap Next.  Use whichever entry method is best for you at the moment, based on how you are holding the phone and what else you are doing at the same time.

That's all there is to it. You get all the information you would expect from a wheel, plus more:

1. ★ Estimated Due Date
   

2. ★ LMP Date
   

3. ★ Conception Date
   

4. ★ 1st Trimester End Date
   

5. ★ 2nd Trimester End Date
   

6. ★ Current Gestational Age
   

7. ★ Current Conceptional Age
   

8. ★ Expected Fetal Length based on standard fetal growth curves
   

9. ★ Expected Fetal Weight based on standard fetal growth curves
   

All this for less than a cup of coffee. Get it from the App Store today!
