The current hardware proves the emergency trigger experience; it is not a finished production ring.
Runs trigger logic and sends SOS signal over Bluetooth Low Energy to the Android app.
Detects the triple-tap gesture used to trigger SOS without opening the phone.
Buzzes to confirm that the SOS trigger was sent.
Safely drives the vibration motor from the board.
Makes the prototype portable after USB-C testing.
A step-by-step illustrated build guide accompanies the prototype.
The wearable is currently a working breadboard prototype, not a production ring. It proves the trigger experience: triple-tap touch trigger → SOS → confirmation buzz.
The production Guardian Ring is a later hardware stage that will require a custom PCB, enclosure, battery optimization, haptics, certification and manufacturing partnership.
This page documents the engineering prototype. The Guardian Ring guide explains the complete phone-connected SOS workflow, buyer questions and current availability without presenting planned hardware as a shipping product.
