Facial Thirds app for iPhone and iPad

Is your face proportional? This application is based on the premise that the ideal facial balance occurs when the face can be divided in to 3 equal vertical dimensions as determined by Leonardo da Vinci.
The application can be used for facial analysis as an educational purpose for determining if there are areas of abundance or deficiencies in a vertical third portion. For example, someone who has worn their teeth down tremendously through the years might have a deficient lower third dimension. This application can help communicate that to them visually.
It is not intended to be clinical or diagnostic to any degree. Really just helping in communication of areas that could be addressed.
