Brilliant

Mobile App Design | UI/UX for iOS & Android

Professional mobile app design for iOS and Android. User research, wireframing, UI/UX design, and interactive prototyping by senior designers.

UX research & user flows

We map the key journeys before designing a single screen — so the architecture serves the user, not the other way round.

Wireframes & interaction design

Low-fidelity wireframes for every key screen agreed before visual design begins.

High-fidelity UI design

Pixel-perfect screen designs for iOS and Android — built on a consistent design system.

Onboarding flow design

The first-run experience designed to get users to value fast — before they lose patience or interest.

Component library

A full UI component library in Figma — reusable, consistent, and built for scale.

Developer handoff

Annotated Figma files with design tokens, spacing specs, and interaction notes — ready for development without guesswork.

Designed for real users

UX research and user flow mapping before a single screen is designed — so the architecture matches how people actually think.

Onboarding that retains

The first session designed to get users to value before they give up — the most important screens in your app.

Native interaction patterns

Gesture navigation, thumb zones, and platform conventions that make the app feel immediately familiar.

iOS and Android

Both platforms designed — with platform-specific adaptations where needed, not just a copied layout.

Developer-ready files

Figma deliverables your developers can build from without constant design questions.

Revisions until it's right

Unlimited revisions included — we iterate until every screen is doing what it needs to.

User research & flows

Key user journeys mapped and agreed before wireframing begins — so the structure is right before the design starts.

Wireframes

Low-fidelity wireframes for every key screen — layout, hierarchy, and interaction points agreed before visual design.

Design system

Colour, typography, and component library built as the foundation for all screen design.

High-fidelity screens

Pixel-perfect UI for every key screen — iOS and Android — built on the design system.

Onboarding design

First-run experience designed to get users to value fast — before they delete and move on.

Developer handoff

Annotated Figma files with specs, tokens, and interaction notes ready for engineering.

Most apps get deleted by Thursday. Design is usually why.

It's not the idea that gets deleted — it's the experience. Confusing onboarding, unclear navigation, and screens that make users work too hard. We design mobile apps that people understand immediately and keep coming back to.

Designed for how people actually use phones

Thumb zones, gesture navigation, and interaction patterns that feel native — not a web design adapted for a smaller screen.

Developer-ready, not just pretty

Figma files with component libraries, design tokens, and annotated specs — so your developers can build from them without constant questions.

Designed to be kept

UX built around how people actually use phones — intuitive, fast, and worth returning to.

Onboarding that works

First-run experience designed to get users to value before they give up.

iOS and Android

Both platforms covered — with platform-specific adaptations, not just a duplicated layout.

Developer-ready

Figma files your engineering team can build from without constant questions.

Delivered in 2-4 weeks

Full app design — wireframes to high-fidelity — within a month.

Unlimited revisions

We iterate until every screen is right. No arbitrary limits.

Do you build the app or just design it?

We design the app — UX, wireframes, and high-fidelity UI. Development is a separate service we can quote for.

What do I receive at the end?

Annotated Figma files with a component library, design tokens, and specs ready for your development team.

Do you design for both iOS and Android?

Yes. Both platforms are included — with platform-specific adaptations where the conventions differ.

How long does mobile app design take?

Typically 2-4 weeks depending on the number of screens and complexity of the user flows.

Do you help with the UX before designing screens?

Yes. User flows and wireframes are part of the process — we map the architecture before any visual design begins.

What if I only have a rough idea of what I need?

That's fine. Discovery and user flow mapping at the start of the project is designed for exactly that situation.

Can I see the designs before you finalise them?

Yes — wireframes are reviewed and approved before visual design begins. You see it at every stage.

What do I need to provide?

A description of the app's purpose, your target user, and any brand assets. We handle the rest.
