How to set up Claude Code for a mobile app
Pick by platform: one skill that builds, one that designs
For Expo, the Expo skills plus Mobile Taste Skill; for SwiftUI, SwiftUI Pro or SwiftUI Expert plus Apple Design Skill; for Flutter, the Flutter team's skills plus Apple Design Skill or UI UX Pro Max. Two skills that both want to set the style will fight.

Say who the app is for, the three or four screens that matter and an app whose feel you like. Mobile Taste Skill makes the agent commit to an app read (kind, audience, feel) and plan the navigation before it writes any code.
Check it on a simulator, not in the code
Run the app in the iOS Simulator, an Android emulator or Expo Go and look at real screens at more than one size. Callstack's agent-device skill lets the agent drive a device and check its own work.
Save the design system in the repository
Mobile Taste Skill writes a MOBILE-DESIGN.md and Expo has an expo-design-system skill. Keep the result in the repository so later sessions, and other agents, follow the same colors, type and spacing. See the CLAUDE.md guide.
Things to know before installing
- Sleek needs a paid account for real use: free accounts get trial credits for about one design run, and Pro is $69 a month, per its skill. Every brief goes to sleek.design.
- Expo's EAS skills use Expo's hosted build and update services, and each Expo skill asks the agent to send feedback through Expo's agent CLI.
- SwiftUI Expert's trace tools need Xcode's xctrace and Python 3; they record and analyse Instruments traces on your machine.
- Claude Code Apple Skills follows its main branch with no version pins, and its own disclaimer says the skills were written with Claude Code's help and may contain inaccuracies.
- Emil Kowalski's mobile-native is for web apps and PWAs on phones, not for native apps.
- None of these are made by Apple or Google, and App Store Review can't promise approval. The registry also lists Sleek's design-mobile-apps with about 1.3 million installs under a repository with few stars; we couldn't verify that number, so it isn't in the list above.
Give the skills an app designer that works every day
A skill makes one session better at mobile work. Crewmark turns Claude Code or Codex into an AI app designer with a goal, such as three polished screens a week, working hours and a board of screens to fix; it wakes on a heartbeat and opens pull requests with simulator screenshots.
Hire the app designer role
Its brief, goal and routine come set up; see the AI app designer and the AI software engineer.

Claude mobile app skills FAQ
What is the best Claude skill for mobile app design?
It depends on the platform. For React Native and Expo, Mobile Taste Skill with Expo's own skills; for SwiftUI, SwiftUI Pro or SwiftUI Expert with Apple Design Skill; for any framework, Apple Design Skill or UI UX Pro Max for the visual side.
Is there an official Claude skill for React Native or Expo?
Expo publishes expo/skills, also available as a plugin in claude-plugins-official, and Vercel and Callstack publish React Native skills. None of them are made by Anthropic.
What's the best Claude Code skill for SwiftUI and iOS?
Paul Hudson's SwiftUI Pro targets iOS 26 and Swift 6.4 and the mistakes LLMs make in SwiftUI; Antoine van der Lee's SwiftUI Expert covers state, performance and Liquid Glass. Both install as plugins or with the skills CLI.
Is there a Flutter skill for Claude Code?
Yes. The Flutter team publishes flutter/agent-plugins, with skills for architecture, responsive layouts, layout fixes, routing, localization and tests, and it bundles the Dart and Flutter MCP tools.
Can Claude Code design a mobile app UI?
With a design skill it does much better than without one: the skill brings the platform's rules and a direction. Check the screens on a simulator or a phone, since the code alone won't show spacing and touch-target problems.
Do these mobile skills work with Codex and Cursor?
Most do. Expo, SwiftUI Pro, SwiftUI Expert, Apple Design Skill and Callstack's skills document Codex or Cursor, and the skills CLI installs SKILL.md skills into dozens of agents.
