I have been a user of this app for >3 years from dermatology residency to clinical practice as a board-certified dermatologist. Very easy to navigate and nearly comprehensive listing of dermatological disease. Whether you are using it as a learning tool (med student, resident) or clinical assistant (ED, IM, dermatology, etc.) it is a “must have” if you encounter cutaneous disease in practice.I use the app multiple times a day and use it to assist with diagnosis, differentials, quick treatment guide, and most importantly as an education tool for the patient. I often will pull up a known diagnosis and show the patient similar photos to their condition from the expansive photo bank to help support a diagnosis. Furthermore, i frequently print out patient handouts for patients so that they have a reliable and physician-vetted document to help answer any questions that remain after our patient encounter.All in all, this is the single best and most used app I use in clinical practice as a dermatologist. Very useful for med students to experienced physicians and I highly recommend.
