I do medical transcription. While doing OB reports, this app comes handy in calculating EDC and current gestational age. Also handy in calculating adjusted age of infants against mother's LMP. For this, I use ultrasound date feature of the app where I enter infant's date of birth. For all the above, I get accurate results. However, never used trimester feature and also saving data for different patients as I don't require those. So cannot comment on that. Otherwise, great app. Keep up the good work.

I have used this app (and the paid version) for many years but the last version is very buggy on the Note 8. Cannot select CRL or IVF tab and cannot change order of fields. Also paid version discontinued.

U70%
by U####:

since using it on the s7 or whether it is due to any recent updates; i cant seem to put delivery dates nor input notes. please fix it. I used to love this app. i am an independent midwife and often need it when i am out and do not have my clients notes on hand. the notes feature helps me inout their data that i can see at a glance without their file. delivery date important too so when i do my postnatal visits I know how old babies are.

U70%
by U####:

This would be great if it worked correctly and didn't have so many bugs. I can't put in delivery dates, nor can I click over to the different tabs. Also, it automatically puts in data if you enter one thing, e.g. if an ultrasound gives a certain GA, and I enter in the date of the US with the GA, then it automatically enters the EDD, LMP, WGA, and date of conception. If the client has a different LMP and I enter that, everything changes. I want to enter each separately without them affecting one another.

Have been using for a few years now. Great app. Was working good on my last phone but not with Samsung s7 not able to b access menu button. Read other reviews. Many more facing similar issue. List of patients are displayed in alphabetic order. I wud like them to be in chronological order according to their date of delivery. This option was available in previous phone. Please please fix this problem.

Hasn't kept up with Android updates. Utilizes a menu only accessible with the menu button, which Android has done away with.
