With the KB mobile app we inform users about the latest trends and topics in the fields of systems for rail vehicles and commercial vehicles. These include, for example, intelligent entrance systems, HVAC systems and also driver assistance systems. Through interactive functions such as commenting and rating, app users can exchange views on these topics and contribute their own opinions. We would like to encourage all readers to actively participate in the communication and exchange experiences. This is how we manage to tell interesting and emotional stories from all over the world in the app. Besides exciting stories, a technical dictionary with voice output offers the possibility to translate technical terms into several languages and is therefore a useful helper.
