The application allows you to regularly check the health of your "moles" without leaving home. Verification is performed by a neural network in a few seconds. The neural network is trained on a database of more than 100,000 images verified and prepared by leading oncologists and dermatologists. The neural network does not make a diagnosis, but, based on a risk assessment, gives recommendations on the need to visit a doctor and choose the right medical specialization. The application reveals the risks of such malignant skin diseases as melanoma and basal cell carcinoma. The project is supported by FSBEI HE PRMU MOH Russia and the Skolkovo Foundation.
