The ItchApp© is an electronic diary designed as an application for the smartphone. It contains seven validated questions regarding the occurrence and intensity of chronic pruritus. A particular feature prevents the retrospective answering of questions, ensuring the quality of the data. This assures subjects, doctors and researchers of accurate information. The ItchApp© has already been validated in Germany and used in randomized, controlled trials.
