App UI/UX Design

App UI/UX Design

Mobile users are unforgiving. They expect apps that are fast, intuitive and beautiful. If your app isn't all three, they leave a 1-star review and switch to a competitor. We design apps that earn the 5-star reviews.

What We Design

  • iOS apps (Apple Human Interface Guidelines)
  • Android apps (Material Design 3)
  • React Native apps with platform-centric UI
  • Wearable and tablet companion apps
  • App onboarding and first-run experiences
  • App redesigns and UX improvements

Why Mobile App Design Is Different

Designing for mobile is not the same as designing for web and scaling it down. Touch targets, thumb reach zones, gesture navigation, one-handed use, platform conventions, limited screen real estate, and variable network conditions — all of these require a fundamentally different design approach.

Our mobile designers have engineered patterns for both iOS and Android and specifically adhere to the conventions that users natively expect. An iOS user expects radically different navigation behaviors than an Android user. Getting this wrong makes an app feel foreign.

Our App Design Process

Rigorous, edge-case tested design engineering.

User Research

We understand who will use the app, what they're trying to accomplish, and what their context is (commuting, working, at home). Context shapes design decisions in ways that aren't obvious until you've done the research.

User Flows & Wireframes

We map every user journey through the app — registration, core feature use, edge cases, error states, empty states. Apps that only design the happy path have terrible experiences when things go wrong. We design everything.

High-Fidelity UI Design

Pixel-perfect designs for every screen state — loading, empty, error, filled, animated transitions. We design components, not just screens, so the development team can build consistently.

Prototype & Usability Testing

Interactive prototypes in Figma let us test the app with real users before a line of code is written. We identify usability problems early when they're cheap to fix.

Design System

A comprehensive mobile design system — colour tokens, typography scale, spacing system, component library, icon set and animation guidelines. This makes development faster and keeps the app consistent as it grows.

Accessibility Audit

We ensure your app is usable by everyone. We test for color contrast, screen reader compatibility, and touch target sizing to meet WCAG standards and platform accessibility guidelines.

Frequently Asked Questions

Clear answers to common questions about our application design processes.

Do you design the app store screenshots and marketing materials as well?

Yes. App Store and Play Store screenshots are often the deciding factor in whether someone downloads your app. We design optimised screenshots and preview videos that communicate the app's value clearly.

Can you improve the UX of our existing app?

Yes — this is called a UX audit and redesign. We review your existing app against usability principles and user feedback, identify the highest-impact improvements, and redesign those flows. We can do targeted improvements rather than a full redesign if budget is a constraint.

How do you handle dark mode design?

We design for both light and dark mode by default. This doubles the design work but it's expected by users on both iOS and Android — especially for productivity and utility apps.
