Ask HN: Building qApp: a minimal queue management platform

I'm currently developing qApp, a lightweight queue and appointment reservation management system for businesses (banks, clinics, shops, etc.). The idea is to let customers join a queue through a simple online form and receive updates via SMS — no apps, no complicated logins.

qApp will support two queue modes:

Normal queue: first-come, first-served.

Reservation queue: customers choose from available time slots.

Each business will also have:

A simple dashboard for managing queues and customers.

A pay-as-you-go model for service usage.

Authentication and session control built-in.

Goal: Create a simple, secure, and affordable solution for small and medium-sized businesses, with minimal complexity both for users and businesses.
