Mobile app design that feels native on every platform

iOS and Android app design that follows platform conventions — not generic templates that feel out of place. HIG for Apple, Material Design 3 for Android, and cross-platform systems that respect both without compromising either.

// Standards

Design standards we do not compromise on

Platform native

We follow HIG for iOS and Material Design 3 for Android — using platform conventions that users have internalised, not generic designs that feel foreign.

Every device

iPhone (all sizes), iPad, Android phones, tablets, and foldables — we design for each form factor explicitly, not just scale one layout.

Design systems

Mobile apps need component libraries with all states (default, pressed, disabled, loading, error). We build them alongside the feature screens.

Dark mode always

Dark Mode is a standard expectation on iOS and Android. We design both themes simultaneously, not as an afterthought.

Accessible design

Dynamic Type, VoiceOver/TalkBack, minimum 44×44pt touch targets, and sufficient colour contrast — designed in, not retrofitted.

Store-ready assets

App Store screenshots, feature graphics, and Play Store listings designed alongside the app — not a rushed afterthought before submission.

Common questions about mobile app design

Do you design for iOS only, Android only, or both?+

All three options. Some clients need both platforms simultaneously (cross-platform approach). Others start with iOS for App Store and add Android later. We advise based on your user demographics and target platform strategy.

What is the difference between HIG and Material Design?+

Apple Human Interface Guidelines define iOS-native patterns: tab bars, navigation stacks, action sheets, and gesture conventions. Material Design 3 defines Android patterns: navigation rail, FAB, navigation drawer. Each creates a distinctly platform-appropriate experience.

Do your designs include Dark Mode?+

Yes — Dark Mode is designed simultaneously with Light Mode for every iOS and Android project. We do not design light-only and convert at the end.

How do you handle App Store and Play Store submission assets?+

App Store screenshots (up to 10 per device size: 6.7-inch, 5.5-inch, 12.9-inch iPad) and Play Store graphics (feature graphic, screenshots per device type) are designed as part of the engagement.

Can you optimise an existing app's UX without a full redesign?+

Yes — mobile UX optimisation is a separate service. We analyse your app analytics, session recordings, and review data to identify high-impact friction points, then redesign those specific flows.

What React Native/Flutter constraints should I communicate to designers?+

Standard React Native and Flutter components should be familiar to our designers. For significant component library constraints (using Expo, NativeBase, or custom component kits), we review these at kickoff and design within or alongside them.
