This app computes the golden ratio of the face from a photo (from camera or photo gallery)
It measures the ratio of facial features and using the golden ratio as a reference, generating the 12 golden ratio scores and the overall percentage of the golden ratio.
100% is the perfect ratio, which means the ratio of the green line over the red line is 1.618. (refer to the report pictures)
Golden Ratio is just a measurement of propositional facial features. It is not an index of beauty.
