I’m looking into something similar. But I definitely think android is the way to go. no ordering/delivery services want to shell out for an ipad. I don’t think an app needs to be built, as you can already save a webpage to the desktop with an icon. what’s really needed is a push notification and a loud noise, to replace email, and a notification tab in the admin panel side bar. Ideally it would flash or turn red, and then once clicked there’s a list of recent orders, and allows transitioning order received to preparation/out for delivery and a payment status. Along with link to order details.
