About KATWARN
Neben den Deutschlandweiten Warnungen durch den Deutschen Wetterdienst (DWD) setzen immer mehr Landkreise und kreisfreie Städte in Deutschland KATWARN für Ihre kommunalen Warnungen ein. Eine Übersicht finden Sie unter www.katwarn.de
Die Benachrichtigungen werden dabei von den jeweiligen Leitstellen der Feuerwehr, des Katastrophenschutzes oder vom Deutschen Wetterdienst ausgelöst.
Zusätzlich dazu können auch Warnungen des KATWARN-Systems in Österreich abonniert und empfangen werden.
Die App verfügt über folgende Funktionen:
• aktive Benachrichtigung (Push-Meldungen) über Gefahren für bis zu acht Orte: neben dem aktuellen Standort (=“Schutzengel“) sieben frei wählbare Orte
• postleitzahlgenaue Warnungen für die gewählten Orte mit Warntexten und farbbasierter Klassifikation der Warnstufe
• kontinuierliche, anonymisierte Aktualisierung der Ortsinformationen, so dass manuell keine weiteren Eingaben zum Standort nötig sind
• sofortige Benachrichtigung bei Betreten eines aktuellen Gefahrenbereichs
• Feedback-Funktion für Rückmeldungen an den App-Dienstleister
Für Fragen und Fehlermeldungen wenden Sie sich bitte an [email protected] oder http://www.katwarn.de, da wir auf Rezensionen nicht antworten können.

About KATWARN
The KATWARN app is provided by CombiRisk Risk-Management GmbH. The content, timing, and scope of the alerts are determined solely by the authorized authorities and security organizations that use KATWARN, not by CombiRisk.
Since responsibility for warnings in Germany is distributed among various agencies depending on the hazard situation, the use of KATWARN may vary regionally. Please contact your local district or city for information on the systems used locally.
KATWARN provides location-based notifications about hazards such as major fires or extreme weather events. Users can choose to receive alerts for their current location and up to seven additional locations of their choice. This selection can be changed, adjusted, or deactivated at any time.
The app offers the following features:
• Active notification (push alerts) about hazards for up to eight locations: in addition to your current location (the "guardian angel"), you can select up to seven other locations
• Postcode-specific warnings for the selected locations with warning texts and color-coded alert levels
• Continuous, anonymized updates of location information, eliminating the need for manual location input
• Immediate notification upon entering a current hazard zone
• Free topic subscriptions (e.g., for food recalls) via the KATWARN website
• Energy-efficient location tracking via base stations and Wi-Fi access points (not GPS) minimizes battery drain
• Feedback function for sending feedback to the app provider
A working data connection (Wi-Fi or mobile network) is required to receive warnings and information.
