Mobile event app

Today, almost every innovative event uses a mobile event app or event web app for communication. We have been successfully developing and programming these event apps for our customers for years. The basis is an event app construction kit with various functions. Each event app can be individually equipped with features for the participants and managed by the customer. In addition to information on the agenda, location, or travel, the apps can also contain event-specific features such as live voting, feedback or download options. Thanks to the latest HTML5 technology, the mobile event app is suitable for smartphones, PCs, laptops or tablets and is therefore flexible in its use and availability for your event.

  • Event app software for your events
  • Manage the content yourself - easily, quickly and securely
  • Personal event app support and many other event services

You can maintain our construction kit for the event app or event web app yourself. We create the basic concept and the basis. Then you get access to the backend to manage the content yourself. You can also reach us by phone for questions and we always offer you the option of having us make adjustments to the app in case of bottlenecks. We offer personal service so that your event is a success.


  • Use the mobile event app for all future events
  • Once created in your company's CD, the event app can be flexibly adapted.
  • Our event app can also be used for trade fairs - we are happy to advise you.

Benefit 2:

Optimize your event invitation

The participant management of an event is always a difficult task. We offer you a full service package and take care of all tasks around the invitation of the participants, the registration, the communication up to the printing of the badges and support on site. For this purpose we create an event landing page and use our event app software. Furthermore, we also offer personal and direct service with our event team, so that every participant can get comprehensive information.

As a B2B agency, we are marketing partners for innovative companies from all industries. We understand the digital economy. Are you looking for the right partner with event expertise in addition to an app?
