The u-Smell-it App is to be used together with the u-Smell-it scent cards as a quick and easy way to help see how well you can smell. Briefly the App reads the unique QR-code of the card with the camera. Then the user scratches and smells different scent windows on the card and using the App picks the best choice between common scents (eg. vanilla, mint, strawberry). The App then tallies the results and indicates if you appear to have a normal ability to smell or a loss-of-smell (anosmia). T
