I need an App that works on both Android and IOS with an updatable database. The business is a food delivery business, so the database should include and have the ability to add restaurant names, items on the menu, and prices. The app should connect to the database to view the restaurants, menus, and prices, and also accept payments (credit cards, paypal, etc). The customers should create accounts before making orders, and store their information like address, name, etc for future ease of ordering. Also since this is a startup it will only cover certain zip codes and with time more zipcodes will be added.
