Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
New: Meeting Point
Save where your household should meet if you get separated during an emergency — a street corner, a relative's house, a landmark — and share it instantly with the people who need to know.
Nearby Facilities is more reliable
Fixed a location-accuracy issue that could search around the wrong spot and miss real hospitals, pharmacies, and shelters near you.
General reliability improvements
Fixed several cases where a failed save could leave the app in an inconsistent state instead of clearly showing what went wrong.
Full language support
Every feature is fully translated across all 23 supported languages.
As always, TerraWarn stays free and works offline when you need it most.
