PregCalc Professional 4.03

the author of this app says:

PregCalc Professional is powerful, easy-to-use and robust. It can calculate a due date and gestational age for an infant, and will provide information about expected weight gain, labs and appointment timing.

Patients can be stored or recalled with ease in the clinic, and the program provides numerous calculations for ultrasound, fetal dimensions and other parameters.

The program now offers fully customizable clinical reminders designed to prompt time-appropriate interventions, infrared beaming so you can share information with other clinicians, the ability to print reports from within the program with ease, and sort patient lists by name or EDD at a touch.

PregCalc was the first dedicated medical application for the Palm organizer, and it is still going strong three years later.

Included in the handheld version is a desktop component that makes sure you can synchronize your information to your PC with no loss of data.
