Mark steps complete, ask for help with a specific step, listen to responses, and share a conversation or checklist when you need to communicate with someone else. PRIVATE BY DESIGN Conversational guidance runs on your device after the model download. Conversations and optional remembered details stay on your device. No account is required. ONE ECHO MODEL There are no confusing model choices. ECHO uses one verified model and can replace older model files after a successful update, helping keep storage under control. BUILT FOR LOW-CONNECTIVITY MOMENTS • Offline emergency guides • On-device conversational guidance after one download • Voice input and read-aloud responses • SOS access to urgent categories • iPhone and iPad support • Performance, memory, heat, and battery optimizations IMPORTANT SAFETY INFORMATION ECHO provides educational suggestions based on established guidance. It does not replace emergency services, professional survival training, or advice from qualified medical professionals. In an emergency, contact local emergency services whenever possible. Conditions differ, sensor readings can be inaccurate, and you remain responsible for decisions made using the app. Some conversational features require a one-time in-app purchase. Core offline emergency guides remain available without the model.
