The Phendo app is available to those over the age of 13 who have had at least one menstrual period in their lifetime. The app has been built through partnering with women with endometriosis throughout the research process, ensuring Phendo is customized to capture the experience of living with endometriosis. Researchers have also included an in-app link to the medical history survey EPHect, created by the World Endometriosis Research Foundation. The purpose of this project is to bridge the gap between what endometriosis patients actually experience and how doctors characterize the disease, through an unprecedented dataset of day-to-day observations, as reported directly by patients about their experience. Using a citizen science approach, the research team have fostered a community, by utilizing social media to ensure the project remains accessible to patients contributing their time by tracking their experience of living with endometriosis.
