NextUp is a walk-in queue and virtual waitlist app for barbershops, salons, restaurants, and service shops. Customers join the line from their phone by scanning a QR code at the door — no app to download. They see their live place in queue, wait anywhere, and get a text the moment it's their turn. Includes a now-serving TV display, door kiosk, staff management screen, and owner dashboard with insights. From $29/month per location with 1,000 texts included.
