Hidden SOS Trigger with Shake & Voice Activation
Guardian Ring is an Android-based personal safety application designed to empower women with discreet, fast emergency alerting. Using shake detection (accelerometer) and voice-activated commands, the app silently sends an SOS alert with real-time GPS location to pre-selected emergency contacts — all without unlocking the phone or opening the app.
