The Kaaka number
↗An Android phone that screens every incoming call, including saved contacts, replies by SMS, texts responders and reports to the control room. Works with the screen locked.
Kaaka · community help line
One call. Location follows.
Kaaka turns one Android phone and a laptop into a help line. A missed call gets an instant reply, the nearest responder is alerted, and the caller appears on a live map. All over plain SMS, with no mobile data needed.

How it works
From a missed call to a closed incident.
Six steps, most of them automatic. The caller never has to explain where they are.
- Caller · any phone
Calls or texts the Kaaka number
A plain call, or an SMS with HELP, SOS or സഹായം for someone who cannot talk.
- Kaaka number
Rejects the call, replies by SMS
Free for the caller. The reply says help is being arranged and, in immediate danger, to call 112.
- Caller's phone
The reply starts the location beacon
With Kaaka Sensors installed, GPS reports flow back automatically. Without it, a link lets them share location from the browser.
- Responders
The nearest responder is dispatched
Distance and ETA by SMS, with a map link and “Reply ACK to confirm”. Nobody answers in five minutes? A reminder goes out.
- Control room
One incident, on a live map
Calls, help texts, alerts and the caller's route are grouped per caller, with the nearest responder drawn on the map.
- Caller or responder
Closed when help arrives
A responder texts RESOLVE, or the caller texts SAFE. Everything stays on record for later.

The full walkthrough.
The Kaaka number, a caller and the control room, recorded end to end: a call, the instant reply, the location arriving, the nearest responder and the incident closing.
Watch it happen
One call, start to finish.
The loop Kaaka runs for every caller: a call, an instant reply, a moving location, the nearest responder, and a text that closes it. Played here in about twenty seconds.

What you get
Three small parts. One help line.
Kaaka Sensors
↗An SOS button, fall detection, a safety timer and an “I'm safe” button. Location reports go out even when Android won't let the app open itself.
The control room
↗Live incidents and routes, history with search, analytics, a responder registry and desktop notifications. Runs on any laptop.
Help, in Malayalam
Someone who cannot talk can text HELP, SOS or സഹായം. Kaaka handles it like a call: an auto-reply, responders alerted, and an incident on the map.
Control room
See every caller. Know who is going.
A browser dashboard that turns calls and texts into incidents people can act on.
Live
Open incidents and routes
Each caller's trail on the map, the nearest responder with distance and ETA, and an alert when the gateway phone goes silent.
History
Every incident, searchable
Search by number, filter by outcome and date, open a full timeline, export to CSV.
Analytics
What the help line is doing
Contacts per day by channel, peak hours, outcomes and a responder leaderboard.
Median time to acknowledgetracked
Incidents with a locationtracked
Auto-replies senttracked
Safety by design
Built for the worst moment, not the best one.
Works without data
Plain calls and SMS
Basic phones, weak signal, no balance for data. A rejected call costs the caller nothing.
Location stays private
Only the Kaaka number can start it
The caller's beacon starts only for a reply from their configured Kaaka number. A stranger cannot request it.
Protected dashboard
Locked before it goes public
The server refuses a public address without an admin token, and replies are rate-limited per caller.
Alongside 112
Never instead of it
Every reply points to 112 for immediate danger. Kaaka adds location, tracking and a responder loop.
For campuses, colonies and families
Run a help line with one phone.
Kaaka is open source. Set up the Kaaka number, add your responders, and open the control room on any laptop.
