Pregnancy Calculator Gyn by BA Dev is a free Android application designed primarily for gynecologists, obstetricians, midwives, and doctors. However, it is also a valuable tool for pregnant women who want to keep track of their pregnancy. With this app, users can calculate gestational age, due day, weeks that have passed, remaining weeks and days, pregnancy days, days until the birth, start date for the second and third trimesters, pregnancy due date, expected delivery date, and much more.

One of the best features of Pregnancy Calculator Gyn is its accuracy. It uses the most commonly used formula to calculate gestational age in weeks and days. Additionally, the app provides two calculations of the term, one based on the first day of the last menstrual period and the other based on ultrasound fetal biometry. This makes it ideal for doctors during prenatal visits and for pregnant women who want to keep track of their pregnancy progress. The app is also simple and very easy to use, making it accessible for everyone.
