ECHO Survival AI

When a signal is weak or unavailable, ECHO helps you think through the next practical step. Open built-in emergency guides immediately, or download ECHO's conversational model once for private, on-device survival guidance. OFFLINE GUIDANCE Explore practical guidance for getting lost, water, shelter, exposure, first aid, fire, food safety, knots, signaling, hiking, and boating. Follow interactive checklists with a highlighted current step, progress, and optional help. Answers identify whether they came from ECHO AI or built-in guides. NAVIGATION WITHOUT A NETWORK Use device sensors and saved local data for coordinates, compass heading, altitude, air pressure, a lightweight reference map, saved places, and breadcrumb navigation. Sensor availability and accuracy depend on your iPhone and conditions. A bearing is not a safe walking route. URGENT HELP Open built-in guidance for urgent situations. Read or copy GPS coordinates with hemisphere labels, accuracy, and fix age. The emergency-call button displays the number selected from your iPhone's region settings; confirm it for your actual location. ECHO does not automatically contact rescuers. PRIVATE BY DESIGN No ECHO account, advertising SDK, analytics SDK, or cloud AI service for conversations. Conversations and optional remembered details stay on your iPhone. Network access is used for optional model downloads only. FREE GUIDES, OPTIONAL CONVERSATIONS Built-in emergency guides remain free. The optional conversational model is approximately 1.3 GB and requires an iPhone with 6 GB of memory or more. Download it on Wi-Fi and try 10 completed conversational responses. A one-time in-app purchase unlocks unlimited conversations. No subscription. Existing lifetime purchases remain restorable. IMPORTANT SAFETY INFORMATION ECHO provides general educational suggestions. It does not replace emergency services or professional training, diagnose injuries, or identify edible plants. Contact local emergency services first whenever possible. Guidance, maps, sensors, and downloaded data may be incomplete or unsuitable for your exact conditions; assess hazards before acting.
