Z Zelnoo Phlebotomist App
Field Collection · Expo / React Native

The Phlebo App is the operating system for the field workforce.

From an 11-step self-onboarding to GPS-guided jobs, an OTP-gated collection workflow, earnings and stock — this is where Zelnoo’s home-collection network does its work. Every step is captured for chain-of-custody, anti-fraud and payout.

The collection flow

A guided, tamper-resistant workflow

The heart of the app: a structured sequence that proves the collection happened correctly — the right person, the right kit, the right sample, all the way to handoff.

1

Arrive

GPS confirms the phlebotomist is at the patient’s location before the visit can proceed.

2

Verify patient (OTP)

An OTP confirms the right patient — the first anti-fraud gate, watched by Sentinel.

3

Safety checklist + kit photo

Gloves, labels, consent and sanitized equipment are checked; a kit photo is AI-verified for completeness.

4

Collect & re-confirm

Samples are collected, then a second OTP confirms completion — preventing post-collection tampering.

5

Transit & deliver

Navigate to the center and scan the samples in at handoff — closing the chain of custody.

The full toolkit

Everything a field collector needs to earn

📝

Self-onboarding

An 11-step flow — personal, address, experience, skills, license, Aadhaar, PAN, bank, selfie and e-sign — with status tracking.

🧭

Jobs & navigation

Today / active / completed queues, full job context, and Google Maps navigation straight to the patient.

🟢

Availability

Online / offline / break toggles and a weekly availability schedule that the Allotment Engine respects.

💵

Earnings & wallet

Per-period earnings, bonuses and deductions, a live wallet balance and full payout history.

📦

Stock & restock

Kit inventory with low-stock alerts, a consumption ledger, and in-app restock requests & orders.

📈

Performance

Acceptance and completion rates, on-time percentage and ratings — the metrics that drive bonuses and retention.

📶
Built for the real world. An offline queue captures status updates when the network drops and flushes them on reconnect, while background location streams to power live tracking and detect GPS spoofing — no job data is lost in a dead zone.
Connected systems & impact

The hands of the operation

The phlebo app is where the platform’s promises physically happen — so it touches dispatch, the patient, the lab, supply, payouts and trust & safety all at once.
