Survival Toolkit

When the signal dies, your tools shouldn't. SurvivalToolKit is an offline-first survival kit for hikers, campers, and travelers. Every essential feature works without internet — only the live weather card needs a connection. EMERGENCY • One-tap SOS — Morse flash, whistle SOS tone, maximum screen brightness, and GPS coordinates saved for rescuers. • Morse Code Flash — LED messaging with 12 preset survival words (HELP, WATER, MEDICAL, FIRE…). • Whistle — Loud tone with the international SOS pattern. • Signal Mirror — Maximum-brightness white screen for visual signaling. NAVIGATION • True-North Compass — Calibration warnings and haptic feedback when you face north. • GPS Coordinates — Decimal and DMS formats. • Route Tracker — Records your path. "Return to Start" guides you back step by step. Lock Screen Live Activity shows distance, time, altitude, and sunset countdown in real time. • Offline Maps — Download regions, powered by OpenStreetMap. ENVIRONMENT • Altimeter & Barometer — Real-time elevation and pressure. • Storm Warning — Detects sharp pressure drops that signal bad weather. • Sunrise / Sunset — Calculated from your coordinates, works offline. • Live Weather — Current conditions, high/low, and next change, via Apple WeatherKit. SURVIVAL GUIDES • First Aid — CPR, bleeding, burns, hypothermia, fractures, snake bites, and more. • Knots — Bowline, Figure 8, Clove Hitch, Sheet Bend with diagrams. • Find Your Bearing — Direction from stars, the sun, or a watch. • Morse Code — Full alphabet, numbers, and signaling techniques. POWER SAVING As your battery drops, sensor frequency lowers automatically so essential tools stay available longer. PRIVACY FIRST • No analytics. No advertising. No tracking SDKs. • No data leaves your device, aside from coordinates sent to Apple WeatherKit. • Saved routes and SOS coordinates stay on your phone. Tools that work when nothing else does.
