Startup Idea : Kitchen Food Creator

An app which would scan grocery receipts and compile an inventory of foods in the kitchen. The app would then compile recipes and track calories for users. Once the recipe is marked as made it could be removed. If an ingredient wasn't used or a new recipe created it could be modified. Recipes and SKUs could be taken from different apps. Home recipes could also be shared with friends. Many apps and websites exist which contain the content for this idea.
