UI/UX-DesignWe make sure that users love your software. cronn develops individual software that makes users happy. Key to this are memorable user interfaces with the best usability and user experience. We will be happy to find solutions that fit your needs and which bring your software to the next UX level: From consulting and analysis, through individual experts for your projects, to the adoption of the UI-UX design for your company.

Our experts for UI/UX take a holistic approach when considering the goals, wishes and needs of the users. In doing so, they observe recognised design rules and always have the satisfaction of the users at the forefront of their minds.
We work with hard numbers and use user research to sound out future users’ preferences. To this end, we conduct surveys, interviews and tests with users according to established methods. We then translate the findings into intuitive and efficient user interfaces.
Our experts analyse existing software for efficient usability. To do this, they identify stumbling blocks of your software and optimise their user interfaces by means of usability tests. These differ depending on the problem at hand and can be carried out by experts, or by users who are specifically observed when using the software.
Our UI/UX designers use fast and cost-effective procedures and tools to visualise ideas and user behaviour. Without writing a line of code, the designers can use it to develop user interfaces and further improve them through user tests. This saves development costs and ensures a positive user experience.
