Expo Mobile App Development Guide (Payments, Ads, Onboarding)

An opinionated ruleset that scaffolds Expo React Native apps with onboarding, a RevenueCat paywall, AdMob banners and i18n.

Dev & CodingIntermediate★ 113⑂ 11AI score 8/10Last updated: Jan 29, 2026

What it does

  • Forces every new Expo project to include onboarding, paywall and settings screens plus a standard src/app / src/context / src/lib / src/locales layout.
  • Provides working snippets for RevenueCat purchases, AdMob banners (including app.json plugin config and test IDs), expo-notifications, i18next localization and Reanimated.
  • Locks in NativeTabs navigation, provider nesting order (Theme → Onboarding → Ads) and the Onboarding → Paywall → Tabs flow.
  • Ships a 'never use' list (AsyncStorage, expo-av, lineHeight, legacy Tabs) and mandatory cleanup steps: npx expo install --fix then npx expo prebuild --clean.

Who it's for

  • Indie devs shipping repeat React Native / Expo Router apps.
  • Anyone needing a monetized app template with subscriptions and ads.
  • Teams tired of re-explaining the same stack conventions to Claude Code.

Examples

  1. "Create a new Expo app" → asks for the bundle ID, runs bunx create-expo, then builds onboarding, paywall and settings.
  2. "Add a banner ad under the tabs" → uses TestIds.BANNER in dev and hides ads for premium users via the ads context.
  3. "Build the paywall" → weekly and yearly plans with a '50% OFF' badge wired to RevenueCat packages.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the SKILL.m folder from the GitHub repo zaferayan/skills into my ~/.claude/skills/zafer-skills/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/zaferayan/skills.git ~/.claude/skills/zafer-skills

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Create the skills folder if needed: mkdir -p ~/.claude/skills
  3. Clone the repo into it: git clone https://github.com/zaferayan/skills.git ~/.claude/skills/zafer-skills
  4. Verify that ~/.claude/skills/zafer-skills/SKILL.md exists.
  5. Restart Claude Code and try a prompt like "Create a new Expo app".
  6. Note: never run npm install inside the skill folder — create real projects in a separate path such as ~/Projects/app-name.
