The Lotus Cars app, originally developed for the Chinese market, was directly translated into English for EU users. This raised concerns about copywriting inconsistencies and usability issues due to regional differences. Development and Product Teams sought my support to address these challenges.

I worked closely with the teams to refine the app for market accuracy and ensure compliance with regional usability standards. To address user flow issues, I conducted user testing sessions, supported by knowledge-sharing workshops with my team, validating improvements and ensuring the app aligned with Lotus user expectations.
My goal was to uncover real-world usability issues and to provide a comprehensive guidance to the product team.

In the first phase, participants were encouraged to interact with the app without any guidance or specific tasks. This allowed me to observe their natural behaviour, initial impressions, and how they navigated through the interface.
This unstructured approach provided valuable insights into their instinctive interactions, highlighted areas of confusion, and revealed features that caught their attention.

The second phase was crucial in assessing how effectively users could complete specific actions. It revealed challenges such as unclear workflows, inefficient navigation, and poor feature discoverability. Participants struggled with inconsistent interactions and confusing terminology, which disrupted task flows and caused frustration.
These findings highlighted the need for streamlined navigation, improved feature visibility, and a more consistent, user-friendly interface.

I started by making key features more discoverable through improved visual hierarchy and clearer layouts. Terminology and labels were refined to ensure consistency and enhance user understanding, making workflows more efficient and intuitive.
Additionally, I made proposals for a polished UI design by suggesting updating iconography, adjusting page layouts, and aligning the overall aesthetic with brand guidelines, delivering a more premium and cohesive user experience.

“In about a year, the app and HyperOS have made significant strides.
The functionality is excellent, and the graphics are beautiful.”
