The inspiration behind this application is the beauty property from the face_detection api. I'm sure there are many traits which determine your beauty rating but from the demo alone I caught myself spending more than enough time trying to make funny faces and score a lower beauty rating (there was no way I was going to get prettier, that's for sure). Then the urge to make an app which would rate you based on your ugliness just called for me, if for nothing else at least a few laughs..
To take this application further, I would like to add additional pug personalities, improve camera features, and greatly enhance the motivational phrase generator.
Lastly, I've chosen to make the application open source as there were a few challenges dealing with cameras on Android which I feel this application overcomes and it would help other developers get started with something similar.
