This App details the science behind the lunar method and explains how you can dramatically increase your chances of conceiving the sex of your preference. It’s a simple and natural method, which has been used successfully by ancient civilizations like the Chaldeans. It is based on the astrological movements of the moon. According to this method, the Moon's position has a great influence on the acidity level of the vaginal fluid.
