ECHO Survival AI
Offline Survival AI-No Signal
Only for iPhone
Free · In‑App Purchases
iPhone
ECHO Survival AI runs entirely on your iPhone — offline, private, and built for real emergencies. No cloud, no account, no subscription.
ECHO Survival AI is the only survival assistant that runs a full large language model entirely on your iPhone — no internet, no cloud, no subscription.
Ask any survival question in plain language. ECHO understands your situation, retrieves the most relevant expert knowledge, and gives you prioritised step-by-step guidance. All of it offline.
POWERED BY APPLE INTELLIGENCE
On iOS 26+ with Apple Intelligence enabled, ECHO runs instantly with zero download. No waiting for a multi-gigabyte model — full AI capability the moment you open the app.
For maximum capability or older devices, download ECHO (Phi-4 Mini, 2025) or ECHO Mind (Llama 3.3 8B, 2025) for the deepest survival reasoning available on any iPhone.
BUILT FOR REAL EMERGENCIES
- SOS button on every screen — tap, select your situation, get an answer in seconds
- Battery-aware responses — ECHO automatically shortens answers as your battery drops so critical information always arrives before the phone dies
- Voice input and output — talk hands-free when your hands are occupied, injured, or cold
- Interactive step mode — procedures render as tappable checklists; check off steps as you go, get targeted help when you're stuck
- Camera context — photograph a plant, wound, or terrain for more accurate guidance
NINE SURVIVAL DOMAINS
Water · Fire · Shelter · First Aid · Food · Navigation · Knots · Signaling · Survival Priorities
Every domain is backed by expert-curated knowledge from the American Red Cross, FEMA, WHO, and wilderness medicine authorities.
PRIVACY FIRST
Zero data collection. No account. No analytics. No ads. No network access required after setup. Every conversation stays on your device permanently.
ONE-TIME PURCHASE

PERSONALISED TO YOU
ECHO builds a profile from your conversations — your experience level, environment, equipment, medical conditions, and communication preferences. Every answer adapts to your specific situation, not a generic user.
OffGrid:AI is a survival education tool. It does not replace professional training, emergency services, or medical professionals. Always prioritise safety and contact emergency services when available.
