“JUP!” – the App That Gets Young People

Amt Süderbrarup

“JUP!” connects young people in Süderbrarup digitally with local activities and opportunities for participation — securely, with ease, and on equal terms.

As part of the Süderbrarup municipal authority’s smart city strategy, “JUP!” was developed as a mobile app for young people aged 12 to 18. The app complements physical meeting places such as the youth center and youth square digitally, makes events and leisure activities easy to find, and creates spaces for exchange, feedback, and participation. The concept, design, and implementation were carried out collaboratively — together with young people and with a special focus on data protection and privacy.

Relatable branding

To ensure that young people perceive “JUP!” as something that is offered to them rather than imposed on them as a municipal tool, we developed its identity and appearance consistently based on the target group. The name, logo, color scheme, and visual language were created in workshops and consultations with young people — modern, clear, and with a certain wink.

The tone also follows this principle: relaxed, direct, and tailored to the target group, without seeming forced. This turns an app into a companion that feels natural and builds trust.

Two views: surveys that have been answered and the details page of an event.

Discover, participate, network

The focus is on features that make everyday life easier and more relevant for young people in Süderbrarup:

  • Finding events and leisure activities that really interest them

  • Surveys and feedback formats to make opinions visible

  • Better understanding of local issues and helping to shape them

  • Improving communication between young people and with youth facilities and services

  • Making information on support services, from specific helplines to addiction counseling, easy to find

In this way, “JUP!” complements the youth center and existing facilities digitally and connects them

Three views: selection of patterned backgrounds, selection of avatars, event overview in dark mode.

Personal rather than generic

Dark mode is now standard for many users, and was also implemented for “JUP!” In addition, we have added elements that give the app a personal touch: customizable backgrounds and a selection of 16 gender-neutral avatars. This allows young people to quickly make “JUP!” their own space.

Second-nature usability

Young people are digital natives. And that was precisely our benchmark. We rely on familiar operating patterns so that “JUP!” works without explanation: clear structure, short paths, fast interaction. At the same time, we have thought through the tone of voice right down to the UI — for example, in surveys that are answered not with a formal “yes/no” but with “JUP” or “NÖ”. This creates a consistent user experience in which language, interaction, and Look & Feel all fit together.

These decisions were not made for young people, but with them. In joint meetings, we refined requirements, prioritized ideas, and translated feedback into design decisions at an early stage. This collaborative approach ensured two things:

  • Content and functions remain close to the lives of young people.

  • The design and language appear authentic because they were not created on the drawing board.

Trust right from the start

When the target audience is aged between 12 and 18, trust is non-negotiable. That’s why we treated data protection and privacy as an integral part of the concept right from the start. True to the motto: as open as necessary, as secure as possible. This applies to the content design as well as the technical implementation and the app's behavior in everyday use.
