PowerWarn is a utility tool available on iPhone that keeps you informed about various hazards such as severe weather, floods, fires, accidents, shootings, or terrorist attacks at your selected locations. Integrated with the modular warning system (MoWaS) of the Federal Office of Civil Protection and Disaster Assistance, PowerWarn delivers nationwide alerts and information precisely to your smartphone, similar to news agencies.

Moreover, it connects to the German Weather Service (DWD) to provide you with relevant severe weather warnings for your subscribed locations. You have the option to disable these alerts if needed. The app offers features like displaying all current notifications, subscribing to multiple locations, receiving alerts via push notifications, and accessing nationwide data from MoWaS and DWD.
