The success of our customers as a profit through good UX from us


Besides our core competence in UI design and development for Windows/.NET, we were also responsible for design and usability for embedded systems, product development and design for ASP.NET applications, prototyping and accompanying reviews. ISO-9241 testing and consulting for new user interface concepts and future visions were also part of the work for this project.


We conceptualized a solution that was implemented using our proprietary content management system (ConDiSys).
Through the solution, all useful information is made available to the various user groups on all possible platforms in a user-friendly, barrier-free and fast way.


Our visual improvements, including animations, have significantly enhanced the user experience of the application. Furthermore, the newly implemented features have increased the usefulness of the software, making the client’s product more attractive to the end user.


As trainers and educators, we know the importance of intuitive learning strategies. Our flashcard app for Windows was born out of the need to constantly educate ourselves. Fast updatability through adaptable software solutions and easier access to new platforms and end devices with intuitive applications.
