Five tools, one live system

Every screen shares the same live data, so a call, a scan or a crowd report shows up everywhere at once.

For pilgrims · any phone

One Number helpline

A free missed call brings a Telugu voice menu: lost person, medical help, nearest toilet or least crowded ghat. The number on the nearest pole tells us where you are.

For volunteers

Volunteer app

The nearest free volunteer gets each request, like a ride-hailing job. Volunteers also report crowd levels every 15 minutes, which keeps the map live.

Open app →
For help desks

Lost & found desk

QR wristbands for children and elderly pilgrims. One scan texts the guardian. Without a band, missing and found reports are matched across all ghats.

For police & RMC

AI

Parking cameras

A small AI model reads each parking camera and marks every bay free or taken. The map shows free spaces, whether the lot is filling, and when it will be full. Only numbers leave the camera.

Built into the map

AI parking, tested on real CCTV

No new hardware: a cheap laptop next to the existing camera, or an attendant with a clicker.

Tested on a public CCTV clip

Every bay, free or taken, every 5 seconds

We ran the counter on a 2.5-minute recording of a real parking lot with 16 marked bays and checked every report by hand. It caught a car leaving and another arriving and leaving.
