This application supports crisis communication processes as part of the emergency management in businesses, government agencies, universities, schools, kindergartens, hospitals, and public institutions. EVALARM is a mobile crisis communication system. When crises develop, the app automatically informs the right group of people and provides them with individual instructions and contact lists. For this, you can easily configure the EVALARM platform in three steps. In the first step, you define your individual crisis scenarios. In the second step, input which individuals or groups should be alerted depending on the crisis. The third and last step includes which instructions and contact lists will be provided to the specific people and groups. EVALARM relies on proven technologies, like the iPhone, in emergency situations to send information faster, more directed and simultaneously to all users who need to be informed. The way we communicate has changed dramatically over the past decade. The Internet and mobile devices, such as smartphones and tablets, allow us to transmit messages in a split second. EVALARM combines these advantages with a fully scalable communication platform. It provides the employees in case of emergency with all relevant and important information and instructions. EVALARM will send all information quickly and accurately no matter where you may be in the world. Continued use of GPS running in the background can dramatically decrease battery life.
