StorkCalendar - Ovulation and Period Tracker, Gender Prediction

From the makers of the advanced StorkDiet app comes StorkCalendar: an app that helps you determine the best time to get pregnant and predicts if it is a boy or girl based on your ovulation cycle. It is based on research that demonstrates that the closer intercourse is to ovulation, the more likely it is to conceive a boy and the further away, the more likely to conceive a girl.
