Aysa is the easy-to-use app to get personalized answers to your skin condition questions. Use the phone's camera to take a picture of your skin concern & Aysa quickly analyzes your photo to provide personalized, helpful information and guidance on what to do next, all while protecting your privacy.

Your skin is unique; skin conditions can look different from person to person. Aysa is diverse too. Its curated library of more than 120,000 medical images includes every skin color and type, and what each of 200 skin conditions can look like at every stage. Instead of just worrying about that rash, redness, or other skin condition, you can get the answers you need with Aysa. Coming soon you'll be able to find a doctor and get telemedicine consultations as well.

Aysa is built on the resources of VisualDx, an award-winning clinical decision support system designed for healthcare workers to enhance diagnostic accuracy, aid therapeutic decisions, and improve patient safety. It draws on the experience of more than 47,000 physicians and nurses, and more than 137 million health searches to be your trusted digital skin health advisor.

Aysa protects your privacy through use of Apple’s CoreML (machine learning), which is executed within the app on your device. The photos of you and your family’s skin issues never leave your phone.

Aysa knowledge and recommendations are based on best available evidence ordered according to standard industry protocols, interpreted by expert opinion. Best available evidence is evaluated by source type, statistical validity, and clinical suitability. Content includes materials adapted from leading textbooks, literature review articles, PubMed, the US Centers for Disease Control and Prevention (CDC), the World Health Organization (WHO), and Infectious Diseases Society of America (IDSA). Leading content sources are reviewed, as is medical literature in general, with ongoing targeted searches in MEDLINE and PubMed. Editorial contributors and staff follow a protocol from most to least evidence: from meta-analyses and systematic reviews of randomized controlled clinical trials to cohort studies to case-control studies to case series to individual expert opinions.

Extremely Helpful

I have lots of weird skin break outs and this app has been wonderful in assisting me with my symptoms journal. Clearly it’s not a diagnosis but it gives me something to report back to my doctor when I see them and because my symptoms are all over the place, it’s nice to have some idea of what’s going on to help connect the dots.


Fast and easy to use

It took less than one minute to send the picture and answer a few questions. The results were immediate. I was given 3 or 4 possible diagnosis. The most likely condition was listed first. I am a nurse. I don’t work in any kind of dermatology setting. The answer was exactly what I suspected. I appreciate the education/information provided but would like to know more treatment options and maybe ask a couple of questions. But it is a free app. The app is exactly as described. I will use it again and I will tell others about it. Thanks for the great app!

Dyshidrotic dermatitis

My mother and I have this condition. About 20 years my mom developed this to a larger degree which one of the top dermatologist in the country couldn’t diagnose. She refused to go back to the doctor because of always being prescribed steroids. When I turned 40 it started to happen to me. Guess what it is Dyshidrotic dermatitis.
