App UI/UX Design

Good design goes unnoticed: the user finds, understands and acts. LaMeDuSe Design crafts interfaces that reduce friction : grounded in research, delivered ready for development.

The problem you're facing

Your users abandon, make mistakes, call support: the interface imposes the system's model instead of fitting theirs. Every friction is a recurring cost : invisible in mockups, obvious in metrics.

Our answer

We design from real users: research, tested wireframes, clickable prototypes, then high-fidelity design documented in a design system development can implement directly.

What LaMeDuSe Design takes care of

  • User research and existing-product audit
  • Tested wireframes and user journeys
  • Clickable prototypes for validation
  • High-fidelity design (mobile, tablet, desktop)
  • Design system: components, tokens, documentation
  • Development-ready specifications
  • Accessibility (WCAG) built into the design

Our methodology

  1. 1

    Immersion & research

    Users, usage contexts, product constraints: design starts with understanding, not drawing.

  2. 2

    Exploration & wireframes

    Sketches, wireframes and journeys tested before any pixel: structure before skin.

  3. 3

    Design & iterations

    High-fidelity mockups, clickable prototypes and iterations with your user feedback.

  4. 4

    Handover & design system

    Source files, documented components and specs ready for development.

Confidentiality

Source files are yours, licences verified for all assets, and confidentiality on your unannounced projects.

Hosting & handover

Deliverables integrate with your tools; for products we develop, the group's European hosting is available.

Design evolution

Design system evolution, new screens and iterations through product versions : with the same design team.

Why LaMeDuSe Design

We design the interfaces of products the group develops and operates: the design we deliver is designed to be implemented : and it is, by teams working alongside ours.

Frequently asked questions

UX handles the experience: journeys, logic, friction. UI handles the interface: colours, typography, components. One without the other gives pretty-but-unusable screens, or usable-but-inconsistent ones. We handle both, in that order.

Yes, systematically: complete Figma files, named components, tokens and documentation. Sources are yours : you're not hostage to the relationship.

Yes: we deliver in the formats development expects (specs, tokens, components), and we talk with your developers during design to avoid implementation surprises.

Depending on scope: a few weeks for a module, 2 to 3 months for a full application with research and design system. The timeline is put in writing at scoping.
