Everything Needed for
Exhibition Management

Four powerful modules working together in real time — keeping your event safe, organised, and running without friction.

📊

Real-Time Crowd Management

Organizers update crowd levels — Low, Moderate, or High — for their assigned area instantly. The main panel receives live data and can reassign staff to hotspots as conditions change on the ground.

Real-time Push Role-based Live Dashboard

🚨

Missing Person Alert System

Raise high-priority alerts with name, age, gender, photo, and last seen location. Every organizer on the ground sees the alert immediately. One tap marks the person as found and closes the report.

From Install to
Full Control

Up and running in minutes — no steep learning curve, no guesswork.

Download & Install the App

Download the Android APK directly from Expo using the link below, or use Expo Go on an iPhone. An active internet connection is required to run the app.

Create Your Account & Choose a Role

Register with your full name, email, and phone number. Select your role — Organizer for ground-level staff, or Main Panel for control room personnel. Each role unlocks a distinct set of features.

Monitor & Update Crowd Levels in Real Time

Organizers head to their assigned areas and mark the crowd as Low, Moderate, or High from the Crowd Status page. The main panel sees every update the moment it happens and can reassign staff as situations evolve.

Raise Missing Person Alerts Instantly

Any organizer can tap Report Missing Person, fill in the details, and broadcast a high-priority alert to every device on the network. When the person is found, a single tap closes the alert and notifies the whole team.

Manage Car Parks Without Guesswork

Organizers at each lot use + and − to keep vehicle counts accurate as cars come and go. The main panel sees live capacity across all lots and can add or remove lots dynamically during the event.
