Multi-function pregnancy calculator.

Calculate dates of pregnancy:
-Last menstrual period (LMP)
-Estimated date of conception
-Weeks gestational age (WGA)
-WGA obtained by ultrasound
-Estimated due date (EDC)
-Adjust length of cycle and luteal phase
-Store multiple patients for easy retrieval
-Full Help pages available
-"Time Machine" mode can calculate "How many weeks will patient be on xxxx date?" and "When will patient be xx weeks gestation?"
-Include extra notes in patient data

Please note: This app may be used for personal tracking purposes, but it is primarily meant to be a clinical tool for professional healthcare workers.


********************
***IMPORTANT NOTE***
********************
This app calculates exactly 280 days (40 weeks) from LMP to EDD, and accordingly for any date in between. Please note that the paper/plastic wheels used by obstetricians or ultrasound technicians are inherently inaccurate. Different pregnancy wheels may vary by as much as 3 or 4 days. Please keep this in mind when comparing the values obtained here to those given in clinic/hospital.

Since updating this on my new Galaxy S7, the features are useless. Every time I press the button to add a delivery date, it tells me split screen is not available. Not being able to add data makes it pretty useless.

My newer samsung phones (Samsung Galaxy S4, Samsung Galaxy Tab4, and Samsung galaxy S6) do not have a menu option so I cannot use any extra settings. It is quite annoying, especially considering it is a paid ap. I'm sure I'm not the only one with this issue.

Like being able to change length of cycle. Suggesting there be a separate place for edc by ultrasound instead of the ultrasound date automatically changing the edc by lmp.

I am an OB nurse and use this app daily. It's fantastic! I am hoping you can make a Kindle friendly app too!!!

N70%
by N####:

I use this app daily and it's one of the reasons I stick with Android! It's the best ob wheel on the market! Can calculate from LMP, EDC, ultrasound report (notorious for leaving off EDC, but providing EGA)... I have my students, residents, & nurses all using it. The NOTES section keeps important patient info at my fingertips! Bravo!

I use this app many times a day on my OB practice.

N70%
by N####:

This AP is great - I use it weekly in the clinic setting. Way easier than the old school paper wheels.

N70%
by N####:

Extremely useful as a quick, accurate tool in clinical practice.

N70%
by N####:

Very responsive developer, and now this app is getting more useful with free data fields, is approaching old Palm apps now.

N70%
by N####:

Good tool for the working obstetrician. Not really a pregnancy app for pregnant women.

by N####:

Use this all the time.
