Write an Android and iPhone application

Hello to everyone, We are looking for an application, for a "dietetic company". The idea is that: When we are at a Restaurant, we take a "Photo" of the menu. "It should scan the page, and "read" the menu. Then it should show for example: - in green color all choices that we have choosen as "healthy" to eat - in orange color all choices that we have choosen as "normal" to eat - in red color all choices that we have choosen as "not good" to eat - in blue, the choices not understood, that were not found on the database (new meal for the application). Thats all.
