My wife and I were fans of the Whole 30 elimination diet. We used it with great success to get ready for our wedding, but found it very difficult to find products in our local grocery store that we could eat while following the very restrictive program.
Together we created an app using the OpenFoodFacts database that leverages computer vision to scan barcodes of grocery store products.
The products ingredients are categorized and if any non compliant ingredients are shown to the user.
