Offline Gemma emergency guidance with bundled public-safety knowledge, visual help, and visible source citations.
Beacon Survival SOS is an offline emergency assistant built for moments when networks are down and every second matters.
Beacon runs local Gemma guidance on your iPhone and retrieves bundled public-safety knowledge before answering. It helps you reason through wilderness survival, disaster response, injuries, burns, bleeding, radiation sheltering, power outages, and other crisis scenarios.
Key features:
- On-device Gemma emergency guidance
- Offline public-safety knowledge retrieval
- Camera or photo-based visual help
- Source citations for medical and public-safety references
- Simple panic-first mobile interface
- 20 UI languages including RTL support
- No account, no cloud inference, no advertising, no tracking
Beacon is not a replacement for emergency services, medical care, rescue professionals, or official public-safety instructions. When communication is available, contact local emergency services or qualified professionals.
