This document describes an app called "The Allergy App" that is being developed to help people with food allergies easily check if food products contain allergens. The app allows users to select their allergies and then scan a product's barcode or search by name to get a quick notification of whether that product is safe for them to eat. It aims to save time for parents who have to carefully check ingredients lists for children with allergies. A mockup shows the proposed simple home screen with buttons for the barcode scanner, product search, and settings screens. The document discusses the app being free and marketing strategies including small mobile ads and social media promotion.
