OBS Calc - Obstetric Pregnancy Calculator

The app interface is compact and user friendly. Works smoothly and without any glitches. Also accurate. Must have for all obstetrics and gynaecology residents and interns!

Excellent App... Just need a setting to choose which calculating option a user want at home.. eg. i want calculate by lmp and calculate by usg date, i dont want other two options... so there should be an option in setting to hide other two options.. That will also give a minimialistic looks to app..

Works well and quickly, ads are not too intrusive, and the ad free option is very reasonable. Really nice that it's easy to get edd, gestation age, LMP calculated by whatever the info the patient has.

I like the app: simple and easy to use, and fast. But could you please include a section for GA on a specific date based on EDD? You have one based on LMP, but I'm more likely to have the EDD on hand, and would rather not go through the trouble of converting through your LMP/EDD calculator.

For checking EDD from previous exams with the previous exam date it is great. I had a patient who spoke limited English and all was on the script was EDD your app only has by LMP and previous exams. I was stuck needing her LMP but she couldn't tell me. So, it won't work in those instances.

Everything is perfect but the cycle duration has set by default at 28 days which gives wrong estimated delivery date and Period of gestation. So please set the cycle duration by default at 29 days. Overall the app is good and i am using this app for last 1 year.

3 stars less for bringing ads UPDATE: thanks for giving the option to disable ads. feature request: allow arranging the sequence of the sections.

It's a very good app it's useful to calculate different things ex. estimated delivery date. Thank you.

Very simple and easy to use app that does exactly what I need. No fuss, no extra learning, just right to the point.

Hi its a very useful app for me. Thank u. But can u pls add a option to select date for which age of gestation is needed. Ex. Today is 22/5 i want to know the gestational age of a delivered baby on 20/4 to know if the baby is full term or pre term.. So if u can add a option to select the date on which gestational age is needed istead of only today it will be very useful. Thank u.

Fair. Glad theres an adjustment for cycle length, but there is an error. Changing cycle length should alter both EDD and the gestational age... This app only adjusts EDD

This app is so well thought out and makes it really easy for moms-to-be (&dad) to plan and prepare for baby to come!!

Easy, efficient. Great for students, interns, and residents!

it's d best app.. bt can u plz add e.g. if a patient is saying she don't know her LMP but her 8th month has already started and already 10 days are over and I want to calcute the period of gestation
