01 — Context and challenge

Accelerate technical diagnostics in a mobile flow.

GradExpert needed a product where users can select vehicle parameters, mark damage zones, and submit service requests without friction. The interface had to be clear enough for non-technical users while remaining operationally accurate.

Main challenge: combine precision input controls with intuitive touch interactions on small screens.

02 — Product goals

What the application had to solve.

  • Fast damage mapping and part selection

    Users should pinpoint affected areas and required parameters in minimal steps.

  • Readable service forms

    Input-heavy screens had to stay clean and legible with clear control hierarchy.

  • Consistent visual identity

    A bold but practical red-black style across mobile screens and product assets.

03 — Solution

Functional UI with strong industrial aesthetics.

We designed a component system focused on form clarity, status visibility, and task speed. Large tap targets, segmented controls, and explicit states made the workflow reliable in real-world service scenarios.

The visual language uses high contrast and directional red accents to keep attention on active controls and key decisions.

04 — UX principles

Interaction framework applied in the app.
