Scan a QR at the door and you are in that shop's line, with a live place number on your own phone. Web push tells you when you are two turns out, then tells you which chair. It buzzes a locked phone in seconds, in English or Spanish. Every barber gets an installable app to run their own queue, track earnings, accept, pass, or finish a cut. Every finished cut can be rated, top barbers rise on the landing page, and a five star finish nudges a Google review. Reputation compounds on its own.
