Interacting with the health insurance company simply, quickly and without red tape. That’s what many people want. BIG makes it possible with its “meineBIG” app. Of course, such an app should be easy to use and offer a positive user experience.

We focused on the user and developed an optimal UX. Find out how we achieved this, what the hurdles were and what exactly our approach was in this case study!

Initial situation

The existing app should be replaced with a better, more intuitive app. The application should convince with very good service. In addition, the competition was launching new apps and it was necessary to “catch up” with the competition.

Our approach


First wireframes and formative evaluations

With first wireframes an early version was tested on concept level with real users.

In these first tests, the user perspective was much better understood and the problems of the own users could be defined more clearly.

Complex processes (such as applications for family inventory maintenance) had to be mapped simply. In addition, many of these processes are very extensive due to legal requirements.

Despite many variables, the use cases were to be mapped in a user-friendly manner.


Visual Design

Taking into account the new navigation, in addition to the interaction concept, a visual look and feel was designed that is based on the existing style guide of BIG Direkt.
Nevertheless, it also takes liberties to reflect a light, round and inviting design that remains consistent to BIG Direkt across media types.

The result

A fresh and clear look. The design represents the BIG very well. The workflows for key functions are now much simpler.

The end result is a clearly structured service app.
