5/5Perfect for tool for the OB setting
As a labor & delivery nurse on a hectic floor, I've managed to find & lose our wheel multiple times during a shift or another nurse swipes it as more patients roll in. Perfect OB wheel app has been a perfect solution. No more lost wheels. Its simple & sleek flow makes it a piece of cake to use. I even use it to keep up with how far along my friends, family, and even myself are during our pregnancies. Highly recommending this app!!

5/5Extremely helpful
I am a nurse in a prenatal clinic and use this multiple times a day. So convenient having everything in one place whether you start with last menstrual period, estimated due date or gestational age, It all works quickly and flawlessly.

I liked it better with the larger font-- the new smaller font is hard for my old eyes :)

5/5Help!
Love the “delivered “ tracking ability, but the latest update is crashing when I try to use it. Please fix. The app is a lifesaver for me!

4/5ACOG
I LOVE this app. However, I do believe that the dating for the trimesters is off. I’m only ever interested in the end of the first trimester and ACOG states that the first trimester ends at 13weeks 6days. This app does not calculate accordingly. Can you please look into this and make a correction if there is a consensus?
