Mobile App Development -- 3

I want to build a platform that will revolutionize the way that people see healthy food and delivery. This app is InstaDiet. This app will include all the basic functionalities of a classic food delivery app but will additionally give the ability to its users to plan their own order and correspondingly the ability for restaurants to list different ingredients and not only pre-defined recipes. The delivery of orders will be handled by the restaurants themselves. Therefore, a second functionality provided by the app will be the option for restaurants to define the radius of service of customers on a map. And correspondingly customers will be informed about which restaurants in their area can serve them. We are interested in the Premium services but we are willing to pay extra for the extra features of the application. So In the attached files you will find the document where the architecture of the application is presented. (InstaDiet architecture). This description is indicative and does not imply that it should be followed automatically. We want the app to have all the functions of a classic food delivery app in addition to the above-mentioned functions. Please pay particular attention to chapters 3.4 and 5.4. please also take a look at Workflow 1 (Chapter 6) and Order editing (Chapter 7)
