Mobile App Design Specialisation
02 / 05

Mobile App Design Specialisation

We design for iOS (Human Interface Guidelines), Android (Material Design 3), and cross-platform – respecting each platform’s native conventions while maintaining a consistent brand identity across every screen.

  • iOS HIG-compliant design patterns and gestures
  • Material Design 3 for Android with dynamic colour
  • Dark mode and high-contrast accessibility (WCAG 2.2 AA)
  • Gesture-driven navigation and bottom-sheet patterns
  • Onboarding flows engineered to reach first activation fast
  • App Store screenshot design and metadata copy
Interaction Design & Motion
03 / 05

Interaction Design & Motion

Static screens tell you what an app looks like – motion tells you how it feels. We design every transition, micro-interaction and feedback animation with a documented motion system so the final product moves with intention, not just decoration.

  • Motion principles document (duration, easing, hierarchy)
  • Micro-interaction design for buttons, inputs and loaders
  • Page transition and navigation animation specs
  • Lottie animation integration guidelines
  • Skeleton loading and progressive reveal patterns
  • Haptic feedback mapping for iOS and Android
Design Handoff & Developer Collaboration
04 / 05

Design Handoff & Developer Collaboration

Most design-to-code friction happens not in the design but in the handoff. We produce developer-ready Figma files with auto-layout, semantic tokens and component annotations – and stay in the sprint alongside engineers to answer questions before they become bugs.

  • Auto-layout Figma components with constraint logic
  • Semantic colour, spacing and type token export
  • Zeplin / Figma Dev Mode annotation layer
  • React + Tailwind design token package
  • Storybook component documentation
  • Weekly design–engineering pairing sessions
App Design Sprint & Rapid Prototyping
05 / 05

App Design Sprint & Rapid Prototyping

When speed matters – a new feature, a pitch, a pivot – we run a focused 5-day design sprint that goes from problem statement to tested prototype without the overhead of a full discovery phase. You get a validated concept you can take straight to engineering or investor demo.

  • Day 1: Problem mapping and How Might We framing
  • Day 2: Competitive review and concept sketching
  • Day 3: High-fidelity Figma prototype build
  • Day 4: Moderated usability testing (5 users)
  • Day 5: Insight synthesis and refined prototype
  • Full sprint report with next-step recommendations

– Why this works

Design that survives the engineering hand-off.

The cost of design is not in the Figma file – it is in the rebuilds that happen when intent, accessibility and motion are lost in translation. We design with the build in mind, in tokens and components engineers can ship without re-interpreting.

01

Tokens, not screenshots

Colours, spacing, type scales and motion are defined as semantic tokens that map 1:1 to Tailwind variables and React props – so the dev team consumes the system instead of pixel-counting from a Figma frame.

02

Accessibility as a default

WCAG 2.2 AA is baked into the components themselves: focus rings, contrast ratios, reduced-motion variants and screen-reader semantics. Compliance becomes the path of least resistance, not a sprint at the end.

03

Motion with intent

Every animation has a job – confirming an action, communicating state, smoothing a transition. We document motion principles alongside type and colour, so the product feels considered everywhere, not just on the hero.

04

Research that ships work

We run lean weekly tests with five users, share clips with the squad, and ship the next iteration the following sprint. Insight stays close to delivery – not buried in a 60-page deck nobody re-opens.

– Frequently Asked

Questions, answered.

How is app UX design different from designing a website?

+

The constraints are different in ways that change the design rather than just the dimensions. Apps are used one handed, often in poor conditions and with interruptions, so reach, tap target size and recovering from a backgrounded state matter more than they do on desktop. Navigation is expected to follow platform conventions rather than a bespoke pattern. There is also an install and permission cost before anyone sees value, which puts far more weight on onboarding and on the first session. Designing an app as a website in a smaller frame is the most common and most damaging mistake.

How do you handle user research?

+

Moderated user testing, review of in product analytics, and stakeholder interviews, weighted toward the questions that actually move product outcomes rather than general usability observations. For an existing app we start with the data you already hold, because drop off points in your funnel tell you where to look before anyone is recruited. For a new product, research focuses on whether the underlying job is real and how people solve it today. We would rather run a small number of well aimed sessions than a large study that confirms things the team already knew.

Do you design differently for iOS and Android?

+

Yes, though less than teams often expect. The information architecture, content and core flows should be shared, while navigation patterns, typography, system components and gestures follow each platform’s conventions, because users judge an app against the other apps on their device. Ignoring those conventions entirely produces something that feels subtly wrong without users being able to say why. We keep one design system with platform specific tokens and components rather than maintaining two independent designs, which would double the maintenance for a difference most users never consciously register.

How do you handle accessibility in mobile apps?

+

WCAG 2.2 AA is the baseline here too, applied through each platform’s accessibility APIs. In practice that means respecting the user’s system text size instead of fixing font sizes, tap targets large enough to hit reliably, sufficient contrast, meaningful labels for screen readers such as VoiceOver and TalkBack, and not relying on colour alone to convey state. Mobile adds cases the web does not: gesture only interactions need an accessible alternative, and dynamic type can break layouts that were designed at one size. We test with the platform screen readers rather than assuming automated checks are sufficient.
