Echo runs on your iPhone
Echo is a custom-tuned local model designed specifically for off-grid and emergency use. It downloads once during installation, then runs entirely on the device. Available in two variants — small and large — depending on your device. Your conversations stay on the phone. Nothing is sent to any server, ever.
- →One-time model download during install
- →Two model sizes — small for older iPhones, large for newer ones
- →Zero network calls after install — fully offline
- →No account, no registration, no analytics
Battery-aware for extended use
In critical battery states, Echo adjusts its behavior automatically — shorter, more direct responses to preserve power. Local inference also avoids the constant network round-trips that drain batteries on cloud-based AI assistants. Designed for trips and emergencies where every percent counts.

Questions
Frequently asked questions
What is Echo?
Echo is the custom local AI model that powers ECHO Survival AI. We built and fine-tuned it specifically for survival, first aid, and off-grid scenarios — drawing on vetted survival manuals and emergency response material. Echo downloads once during installation and runs entirely on your iPhone afterward. No internet, no server, no third-party API.
Does ECHO Survival AI work without internet?
Yes. ECHO Survival AI is designed to work completely offline. Echo, the local model, downloads once during installation. After that, no internet connection is required at any point. All AI processing happens locally on your iPhone.
How much battery does ECHO Survival AI use?
Echo adjusts its behavior based on your device's battery level. In critical battery states, responses become shorter and more direct to preserve power. Local inference also avoids the constant network round-trips that drain batteries on cloud-based AI assistants. Battery impact varies by device — newer iPhones with the Neural Engine handle Echo more efficiently than older models.
What devices are supported?
ECHO Survival AI works on every iPhone. Echo, the local model, scales its behavior to your device — older iPhones use a smaller model variant; newer iPhones run the larger one with faster responses. The app picks automatically based on your device's capability.
Is this a replacement for professional survival training?
No. ECHO Survival AI is a supplemental guidance tool designed for emergency situations when professional help is not accessible. It's based on vetted survival manuals but cannot replace hands-on training or professional emergency response.
Does ECHO Survival AI collect any data?
No. ECHO Survival AI collects zero data. No accounts, no analytics, no tracking, no cloud processing. Your conversations and usage patterns never leave your device. This is a core privacy commitment for emergency preparedness scenarios.
