How the Kavach Band detects a fall
The band notices the shape of a fall
An accelerometer and a gyroscope in the band watch for the pattern a fall leaves: a sudden drop, a hard stop, and the wrist ending up at a different angle from where it started. A tap on a table or a brisk walk does not match that pattern, so they are ignored.
A 30-second countdown starts, with a buzz
The band vibrates so the wearer knows it has flagged a fall. A single press of the button cancels the countdown. That press is the only thing anyone has to learn.
If nobody cancels, the band raises an SOS on its own
At the end of the 30 seconds the band sends an SOS over its own 4G connection, with the wearer's live location, to up to three emergency contacts. No phone, no app and no button press is needed for help to go out.
The family gets a push notification and an email
Each contact receives the alert in the Kavach Care app and by email, with a map that keeps updating. SMS and WhatsApp alerts are not live yet. The nearest person moves first and everyone else can see what is happening.
Where it works, and where it can be wrong
It works
- In the bathroom. The band is sealed against splashes and handwashing, so it stays on where most serious falls in Indian homes happen. Take it off for bathing and swimming; it has no immersion rating yet.
- Without a phone. The band carries its own SIM, fitted at the factory. The wearer carries nothing else.
- Without a plan. A fall alert is an alarm, and a plan never gates an alarm. SOS and fall alerts work on the free tier for the life of the band.
- Across any distance. A daughter in Bengaluru or Boston gets the same alert at the same moment as the neighbour who can reach papa first.
It can be wrong
- A soft fall onto a bed, a sofa or a carpet may not match the pattern and may be missed.
- A hard knock, a two-wheeler ride or a car on a bad road can look like a fall and start the countdown. One press cancels it.
- A slow slump from a chair, or a faint, does not have the sudden drop a fall has.
- The band must be on the wrist. The family is told when it comes off, but a band on the bedside table detects nothing.
- The hours on the charger are uncovered. A charge lasts up to 24 hours, so most families charge it during the afternoon rest or while the wearer sleeps.
Treat a fall alert as a reason to call the wearer, not as proof. If the call is not answered, the live map tells you where to send help.
Tested, not certified
We say this on every page that mentions fall detection, so it bears repeating here. The detector has been through our own trials, including a founder test in October 2026, and it raised the alert. It has not been certified by any standards body, and we do not publish a detection rate or a false-alarm rate, because we do not yet have figures from a large enough sample to stand behind. When we do, they will be on this page with the sample size next to them. Until then, the honest description is a second chance, not a guarantee.
If you want the longer version, the sensors, the physics of a fall and why cheap detectors fail, read how fall detection actually works.

Common questions
What happens if my mother falls and cannot press the button?
The band starts a 30-second countdown with a buzz. If she does not cancel it, because she cannot reach the button or is unconscious, the band automatically sends an SOS with her live location to up to three family members. No button press is required for help to go out.
Is Kavach's fall detection certified?
No. It has been tested in our own trials, including by the founder, and it works. It is not certified by any standards body and we do not publish a detection rate, because we do not yet have a figure we would stand behind. Treat a fall alert as a reason to call the wearer, not as proof that they have fallen.
Will it go off by mistake?
Sometimes. A hard knock or a bumpy ride can start the countdown. The wearer cancels it with one press, and nothing is sent. If you get repeated false alerts, write to support with the times and we will look at the band's data.
Does fall detection need the paid Safety Plan?
No. A plan never gates an alarm. SOS and fall alerts work on the free tier for the life of the band. The paid plans add live tracking, longer route history and faster reporting.
Does it work in the bathroom?
Yes. The band is sealed against splashes and handwashing, so it stays on in the bathroom, where most serious falls at home happen. It has no immersion rating yet, so take it off for bathing and swimming.
Band or watch for an elderly parent?
Both detect falls and both raise an SOS if the countdown is not cancelled. The band is lighter, has one button and no screen to learn, and is the right choice for a parent who has never used a smartphone. The watch adds two-way calls and an SOS that dials the family in turn, for a parent who wants to talk, not just be found.
