"KATWARN" is an app for communicating hazard and disaster warnings.

Features & Capabilities

KATWARN delivers official hazard and disaster warnings, recommended actions, and continuous updates to citizens in Germany on behalf of authorities and security organizations. The app forwards alerts from regional agencies and the Federal Government’s Modular Warning System (MoWaS/NINA), letting users get timely, postcode-specific information and color-coded severity levels for up to eight locations.

KATWARN uses energy-efficient, anonymized location tracking (cell/Wi‑Fi) to minimize battery use and can notify users immediately when they enter an affected area. Features include push notifications, continuous updates, optional topic subscriptions (e.g., food recalls), and a feedback channel. The service is provided by CombiRisk Risk-Management GmbH; alert content and timing are controlled by authorized authorities. For support visit http://www.katwarn.de or email support@katwarn.de.

User Reviews

Users appreciate KATWARN for providing real-time warnings and visual maps of affected areas during severe weather. However, the app suffers from excessive and repetitive notifications about 'Guardian Angel' activation, which many find annoying. Additionally, location service problems and app freezes hinder usability. Some users report missing critical alerts and poor customer support, causing them to uninstall the app despite its potential usefulness.

Pros

Provides real-time messages of potential risks and warnings.
Shows affected areas on an easy-to-understand map.
Useful during severe weather events like tornadoes with timely alerts.

Cons

Excessive notifications, particularly about 'Guardian Angel' activation, leading to notification spam.
Location services and permissions issues causing the app to not display correct location or warnings.
App freezing or poor performance during location selection and other interactions.
Lack of timely updates or missing critical warnings during severe weather events.
Poor customer support and unresolved bugs, leading to user frustration and app uninstallation.

Recent reviews

Just getting an endless loading symbol when trying to start the app. I highly suggest to use NINA instead of this potentially dangerous waste of resources.
