The Mobile App allows you to control the settings on your smartphone camera, while keeping the same settings for both short-wave ultra-violet (SWUV) and long-wave ultra-violet (LWUV) illuminations. The settings are controlled for exposure, ISO, colour temperature and focus. The two images (short-wave and long-wave) can then be compared either through alternating views or using a slider. Images with SW and LW labelling can be saved to your image gallery.
