Queue

I built Queue to fix this: the owner creates an order and shows a QR code, the customer scans it, watches a live wait timer, and taps Notify me. The owner taps Ready once and a Web Push notification reaches the phone even with the browser closed. I chose Web Push after comparing four channels because it costs nothing per message, and the app collects no email address and no phone number.
