Signal Radar · Offline SOS AI

Going solo into the wilderness, alpine trails, deep-water fishing, cross-border travel, or disaster zones? When a phone loses signal, the people who care about you may not know where to look. Signal Radar is a safety companion built for the moments when ordinary connectivity fails.

BACKGROUND SIGNAL MONITORING Signal Radar checks cellular availability in the background and records the latest known state. When coverage returns, it can trigger your configured emergency workflow with your location and a map link.

AUTOMATIC SOS Add emergency contacts and configure alerts in advance. If a serious signal event is detected, the app can prepare and send an SOS message with your identity, time, coordinates, address when available, and map link.

OFFLINE AI FIRST AID The on-device AI assistant works without a network connection. Ask practical questions about first aid, injuries, exposure, navigation, and survival. Answers can use your downloaded offline knowledge packs and show the relevant source entries.

OFFLINE SURVIVAL LIBRARY Explore more than 60 guides covering first aid, snake and animal bites, water, fire, shelter, navigation, vehicles, weather, travel health, and emergency preparation. Download optional knowledge packs for deeper local reference.

EMERGENCY TOOLS Access regional emergency numbers, manage contacts, review monitoring events, and copy your latest coordinates or map link for messages in other apps.

PRIVACY Signal checks, location handling, contacts, and offline AI processing are designed around on-device use. You control whether lock screen and Dynamic Island status are shown.

IMPORTANT Signal Radar is a preparedness and communication tool. It cannot guarantee signal, delivery, rescue, or medical outcomes. Keep your phone charged, carry appropriate equipment, and contact local emergency services whenever possible.
