I built a walk-in waitlist app for barbershops and salons

Walk-in shops have a quiet problem: someone walks in, sees a full waiting room, and leaves. I built NextUp Walk-in so people can hold their place in line from their own phone instead.

How it works

A customer scans a QR code (or opens a link) and joins the line. No app to install.
They see a live wait time while staff call people from one screen.
A waiting-room TV shows who is next.
The same line runs on a door tablet, the staff screen and an owner dashboard, all kept in sync.

It is made for barbershops, hair and nail salons, tattoo studios, pet groomers and similar walk-in businesses.

Under the hood

.NET 10 minimal APIs with raw Npgsql on PostgreSQL (no ORM)
An Angular app using signals
Native TV apps for Apple TV, Roku and Fire TV, plus an Android app

Pricing

There is a free plan (one location, 50 check-ins a month). Paid plans start at $29 a month per location, and there is a 14-day trial. You can try the live demo line without signing up: https://nextupwalkin.com/demo

I would love feedback from anyone who runs or works in a walk-in shop.
