• 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.

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.
