We hope you never need this app. We built it for the moment you do. THE PROBLEM YOU CAN'T SEE In the backcountry, signal doesn't come back gracefully. It flickers — appears for half a second, vanishes, returns ninety seconds later for a second and a half, gone again. You can't catch it. Your hands are frozen, your phone is on your hip, the window closes before you can open your messages. Signal Radar's only job is to catch that window. It runs silently in the background, 24/7, scanning cellular for the tiniest flicker of reconnection. The instant signal returns — even for a fraction of a second — a pre-composed email fires to your trusted contacts: GPS coordinates, altitude, timestamp, and any custom message. Locked screen, dead-tired, or unconscious — it still works. WHEN THE SIGNAL ISN'T COMING BACK Sometimes you're not waiting for rescue. You're waiting for yourself. Snake bite. Broken bone. Burned hand. Hypothermia setting in. What do you do in the next sixty seconds? We packed Gemma 4 — Google's on-device LLM — directly into the app. Photograph a snake, the model identifies it across 50 venomous species worldwide and walks you through first aid. Photograph a sting, it identifies 40 bees / scorpions / spiders / marine toxins. Type "deep cut, my own thigh" — it talks you through pressure points, tourniquet thresholds, when to release. CPR, severe bleeding, lightning, hypothermia, heat stroke, burns, getting lost — every scenario, illustrated, on-device, zero internet. Apple Vision plus feature-vector matching drops cross-category errors to near zero. GLOBAL EMERGENCY HOTLINES · 100+ COUNTRIES Police, fire, ambulance, coast guard, fraud, consular protection — exact digits, no guessing. Say "chest pain" and the medical line surfaces. Cross a border and the local hotlines load instantly. PRIVACY & DIAGNOSTICS AI inference still runs on device. To diagnose answer quality, retrieval matches, and crashes, text questions and AI answers may be uploaded asynchronously to our cloud telemetry endpoint with anonymous identifiers. Photos, raw voice recordings, location history, and signal history are not uploaded as AI telemetry. We use Firebase/Umeng for feature and stability analytics, and we do not sell your data. THE PROMISE We genuinely hope this sits unused on your phone for years. But if the day comes — the night your foot slides off the trail, the moment the dust storm rolls in, the second your boat takes water — we want Signal Radar to be the one light still on. Built for the day you hope never comes. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
