Skin Scan is a new Apple App Store application that analyses moles and marks on the skin. A simple photo is analysed and compared with a previous photo using a custom-designed algorithm that calculates the fractal dimensions of the mole. The app alerts the user if they need to visit a dermatologist.
The creators of Skin Scan, including two dermatologists and two mathematicians, maintain that it is well worth spending ten minutes analysing your skin if it can save ten years of your life. Skin Scan was not designed, however, to replace regular medical check-ups.
