Redesigning Toyota's car companion app entails integrating several new features and establishing a new global design system accessible to distributed design teams. The current app in the market has become bloated with added features, leading to a cumbersome user experience. This issue has arisen due to the absence of traditional testing and iterative refinement processes. With engineers transitioning the code base to Flutter, there is an opportunity to streamline components and establish a cohesive system.
Using the brand guidelines we developed an atomic structure for Toyota and Lexus, forming a design system and using that to structure the app.
Using the same participants earlier in the project we ran prototype scenario tests to get feedback on the navigation and content structure.
The basis of a new design system was created with two apps.
