04 · Service line
UX and UI design for phone, tablet and foldable, validated with real users and delivered as a design system your engineers can build from directly.
What's included
04.1
One product, designed natively for every size class.
Adaptive layouts that respect each platform: bottom navigation on phones, rails and multi-pane views on foldables and tablets, and continuity as users move between postures.
Deliverables
04.2
Test with users before engineering starts.
Interactive prototypes tested with representative users on real devices, with findings turned into design changes before they become expensive code changes.
Deliverables
04.3
Consistency across apps, teams and years.
Tokens, components and documentation shared between design and code, so every new screen ships faster and stays on brand across platforms.
Deliverables
04.4
Usable by everyone, defensible in an audit.
Accessibility designed in from the first wireframe: contrast, focus order, dynamic type, screen reader semantics and touch targets that meet WCAG 2.2.
Deliverables
How we run it
Define flows, information architecture and size-class behavior.
Build interactive prototypes for the riskiest journeys first.
Test with real users on phone, tablet and foldable.
Hand off a documented design system engineers can build from.
