KATWARN is a service app for transmitting danger and disaster warnings within Germany. The app provides location-based notification of danger alerts, such as heavy fires or extreme weather, with the ability to always be informed for the current location and additionally for seven other, freely selectable places. This selection can be canceled, adjusted and switched off at any time. Using energy-efficient location via base stations and Wi-Fi access points (and not GPS) will only marginally impact your battery.

Various facilities may be distributed, the use of KATWARN
differ regionally. In addition, KATWARN disseminates the warnings of the federal modular warning system (MoWaS / NINA app) and is also used internationally.

The app has the following features:

• active notification (push messages) about dangers for up to eight locations: seven locations besides the current location (= "guardian angel")
• postal code-specific warnings for the selected locations with warning texts and color-based classification of the warning level
• continuous, anonymized updating of the location information so that no further input to the location is required manually
• Immediate notification when entering a current danger area
• Feedback function for feedback to the app provider
