In the course Application Design the challenge was to redesign a smartphone application. The goal of the course was to apply basic user-centered methods, iterative product development, prototyping and design in the mobile usage context. We chose the local taxi app 50/50-Taxi. According to the user-centered design approach, we understood and defined the user and analyzed his needs depending on the context. By reorganizing the information structure, we optimized user flows and added user-relevant functions. In this way, a coherent and function-oriented interaction and visual design was developed. Furthermore, product hypotheses were validated and iterated by constant user testing. Finally, a new user experience emerged.

About the 50/50 app
For more than 16 years, the “50/50-Taxi” has been driving young adults home safely late at night and for half the price. The first 50/50-Taxi app of the Ostalbkreis district was developed in April 2015. In the app, people need to register and and install an electronic authorization card on their smartphone. When they get into the taxi, they show the card, activate the app and scan the QR code of the taxi’s order number with their smartphone.
