Customer App — Zelnoo

The Customer App is a diagnostics marketplace in your pocket.

A “Zomato-style” patient app: search tests or snap a prescription, book a home collection or center visit in under a minute, pay securely, then watch your phlebotomist arrive on a live map — and read your results with AI-flagged insights when they’re ready.

The demand side of the whole machine

A single patient booking sets off a chain reaction across dispatch, the lab, payments and reporting — the app is where it all starts and ends.

→ ALLOTMENT

Dispatch

A paid booking triggers the Allotment Engine, which picks the phlebotomist the patient then tracks live.

↔ PHLEBO APP

Collection

The phlebo’s status and GPS stream into the patient’s tracking screen; OTP exchange confirms identity at the door.

→ LAB PORTAL

Fulfillment

Orders flow to the center; processing states push back as live status updates the patient can see.

↔ PAYMENTS

Checkout

Secure gateway integration with deep-link return, retry and refund handling completes the booking.

↔ AI / REPORTS

Insights

Claude reads prescriptions and report markers, surfacing auto-selected tests and abnormal-value flags.

↔ SUPPORT

Care

Tickets and live chat connect straight to the Support system with the patient’s order context attached.
