Skin cancer is the most common cancer in the U.S., and estimates indicate that nearly 9,500 people are diagnosed with skin cancer every day, according to the American Academy of Dermatology. But how can you tell if that freckle is really getting bigger, or if it’s something you should be concerned about?

SkinVision, an app from a company based in Amsterdam, lets you take a medical-grade photo of your skin with your smartphone, and the app can then detect possible skin cancer and determine whether you should see a doctor. You can also keep track of changes in any moles or other skin abnormalities over time, as SkinVision provides a photo archive that uses an algorithm to note any changes or developing issues. While the company notes the app isn’t a substitute for a visit to a medical professional, it may be able to help prevent malignant cases of skin cancer over time.   SkinVision is rolling out to U.S. customers in 2017 in the Apple App Store and Google Play.
