For business · lone workers
For night shifts, remote sites, restricted-phone production floors and care staff. A standalone GPS alarm with live position and two-way voice — no phone required — so nobody is on their own when something goes wrong.
During an alarm
1Hold SOS for five seconds — or the alarm raises itself when the device detects a fall.
2The colleagues you nominated get the alarm, and a two-way voice channel opens on the device so the worker can be heard, not just located.
3The alarm appears in the app with the live position, so whoever responds knows where to go.
The hardware
Every alarm lands in the same app, whichever device raised it — so a site can mix them without staff learning two systems.
Standalone · no phone needed
Own SIM (4G), GPS, two-way full-duplex voice and automatic fall detection in one wearable. Hold SOS for five seconds, or it alarms on a fall.
$105 per device · connectivity quoted per deployment

Where it is used
The common thread is not the industry. It is that the person at risk is momentarily out of reach of everybody who could help them.
Night workers at Hamlet Factory carry the GPS button on shift.
The GPS button works on its own connection, so it needs no personal phone — and no signal on one.
Pilot underway at Grundfos India, where mobile phones are restricted.
Two-way voice means the responder can hear the situation instead of guessing at it.
Alarm with live position, whether or not the worker carries a phone.
In use at Filadelfia Epileptic Hospital and a doctors’ clinic in Gandrup, Denmark.

Staff will ask whether this is a tracker. The honest answer decides whether the buttons get worn or left in a locker.
