From SuperMagnus Software:
Growth Charts is a Macintosh OS X application that allows for tracking and charting of growth data for children/teens from birth through age 20 years. It can track weight, length/height, head circumference, and even body mass index (BMI). Additionally, the predicted adult height can be estimated. Using the program, data can be stored, edited, and subsequently plotted on growth charts. The growth charts come from the Centers for Disease Control (CDC) and are the same ones used by pediatricians throughout the United States to monitor for abnormal or concerning growth patterns. If you have ever been curious to follow the growth of your child (or yourself) the same way that the doctor does, this program will allow you to do that using the same charts that your doctor probably uses.
