Medical Intern, Brazil
"I have been working with Family medicine in a rural city in Brazil and Dem Dx has been such a life safer! It was the first time that I had autonomy to get my own clinical decisions when I wasn't feeling confident enough to do so."
4th Year Medical Student, Imperial College Medical School
"Dem Dx is a unique app that effectively aids my clinical learning by giving me logical pathways to help efficiently narrow down diagnoses. Most importantly it ensures I appreciate the journey to a diagnosis, rather than simply the end result."
