offgrid:AI delivers offline survival guidance with ECHO—battery-aware, safety-first, and designed to refuse when uncertain
No signal. No cloud. No problem.
OffGrid: AI works entirely on your iPhone — no internet required,
ever. When you're lost, stranded, or the grid goes down, ECHO is
already there.
ECHO : Your On-Device Survival Expert
ECHO is an offline AI that thinks, adapts, and responds to your
exact situation. Not a static checklist. Not a read-only field
guide. A conversational expert that understands context, asks the
right questions, and gives you step-by-step guidance — all running
locally on your device.
Try ECHO free for your first 10 queries. No purchase required to
start.
9 SURVIVAL DOMAINS
- Water — finding, purifying, rationing
- Fire — starting and maintaining in any condition

BATTERY-AWARE INTELLIGENCE
ECHO monitors your battery in real time and shortens responses
automatically as power drops — so the most critical information
always reaches you before the device shuts down.
