About this app

KATRETTER alerts volunteers in emergencies and emergency situations in the immediate vicinity
When rescuing people, every minute counts. In many emergencies or crisis situations volunteers could help with their different skills and abilities. The KATRETTER system helps the emergency services to inform the right volunteers in a matter of seconds - mobile, legally secure and location-specific.
In emergencies such as cardiac arrest, but also in other crisis situations, the control center alerts volunteers by smartphone app in the vicinity of the mission. According to the registered qualification, the volunteer "first aiders" begin rescue operations, even before the professional rescue teams arrive. Or, as dedicated "helpers", they support the use of simple activities. Whenever the helpers are alerted, the KATRETTER system decides anonymously and after registered qualification.
Different missions require different types of voluntary support:

First responders have training in the field of medicine or work in rescue services and can, for example, initiate first resuscitation measures. For this they have to register as first responders - of course for free.

Assistants also contribute without any specific knowledge: whether filling sandbags with a flood or providing first-time support for insecure people in crisis situations. Accessaries can use KATRETTERs free of charge without specifying a specific qualification.

KATRETTER is a cooperation between the Berlin Fire Department, the non-profit research institute Fraunhofer Institute for Open Communication Systems (FOKUS) and the non-profit CombiRisk GmbH.
