The University of Michigan Health System developed a free mobile app for iPhone and iPad users to track skin changes and monitor for signs of skin cancer. UMSkinCheck lets users create a photographic baseline of skin lesions and then reminds users to check the lesion for changes over time. If a mole or lesion changes, the user can share the photo with a dermatologist to determine next steps. The app also takes you step by step through a self-exam and will calculate your risk of developing melanoma. It also has examples of common skin lesions and takes you through the ABCDs (asymmetry, border, color, difference) of melanoma. Users can get sun safety and sunscreen tips as well. Download the UMSkinCheck app on iTunes.
