AllerScan is a smart mobile application designed to help people with food allergies or dietary restrictions make safer food choices. The app allows users to scan food product labels or ingredient lists using their smartphone camera, then analyzes the ingredients to detect potential allergens based on the user's personal allergy profile, such as peanuts, milk, eggs, soy, gluten, tree nuts, and other common allergens. It provides clear and easy-to-understand results, helping users quickly determine whether a product is safe to consume and reducing the risk of allergic reactions.
