# Expo Mobile Monetization

> Expo React Native mobile app development with RevenueCat payments, AdMob ads, i18n…

A complete, opinionated stack for shipping production Expo React Native apps with monetization built in: RevenueCat subscriptions, AdMob ads, i18n localization, a swipe onboarding flow with fullscreen video, a paywall and native tab navigation. It enforces the exact libraries, screen structure and configuration that pass App Store review and avoid the crashes (like missing AdMob config) that sink new apps.

## Use cases
- Scaffolding a new Expo app with onboarding, paywall and settings
- Integrating RevenueCat subscriptions with entitlement checks
- Wiring AdMob banner ads that hide for premium users
- Building swipe onboarding with fullscreen background video
- Setting up i18n with correct Turkish localization
- Native tab navigation with platform-specific icons

## Benefits
- RevenueCat entitlement model gates ads and paywall correctly and keeps restore-purchases working (an App Store review requirement)
- Mandatory AdMob app.json config avoids the GADInvalidInitializationException crash that kills new apps
- Onboarding-to-paywall pipeline clears stack history so conversion flow can't break with a stray back button
- Ad-premium toggle pattern removes ads instantly the moment an entitlement changes

## What’s included
- Required screen scaffold: onboarding (video), paywall, settings with reset
- RevenueCat entitlement and restore-purchases integration with isPremium gating
- AdMob banner implementation with TestIds in dev and useAds context for premium hiding
- NativeTabs cross-platform navigation with SF Symbols and Material icons
- i18n setup with strict correct-Turkish-character localization rules
- Forbidden-library and reanimated-hook guardrails plus post-creation cleanup steps

## Who it’s for
Mobile developers building monetized Expo React Native apps who want a review-ready stack with subscriptions, ads and onboarding done right.

## How it runs
From bundle ID to a prebuild-clean release candidate, this is one fixed assembly line for an Expo app: onboarding, paywall and settings screens, RevenueCat and AdMob wired in, and the known crash traps banned outright.
1. Starts by asking for the bundle ID, scaffolds with create-expo, and writes the ID into app.json for both iOS bundleIdentifier and Android package before any feature code.
2. Builds the three mandatory screens: a swipe onboarding with fullscreen background video and gradient overlay (expo-video VideoView, looped and muted), a RevenueCat paywall with weekly and yearly options where yearly carries the discount badge, and a settings screen with language, theme, notifications, remove-ads and reset-onboarding.
3. Wires monetization end to end: required libraries installed via npx expo install, the AdMob plugin block added to app.json (test App IDs in dev, skipping it crashes with GADInvalidInitializationException), and the banner ad rendered under NativeTabs only when the useAds context says shouldShowAds, so premium users never see it.
4. Enforces the conversion flow: onboarding completion persists, then router.replace pushes straight to the paywall with no back path, and purchase or skip lands in the main tabs; navigation is NativeTabs only, never the JS bottom-tabs.
5. Applies the hard bans during implementation: no AsyncStorage (expo-sqlite localStorage polyfill instead), no lineHeight styles, no expo-av, no Reanimated hooks inside callbacks, and tr.json written with correct Turkish diacritics.
6. Closes with the mandatory cleanup pass: delete the conflicting src/app/index.tsx when tabs exist, grep out every lineHeight, then run npx expo install --fix and npx expo prebuild --clean so the native folders match the final config.

## FAQ
### I already have an Expo app: can I add just the paywall and ads, or is it new-projects only?
The pieces are modular enough to retrofit: RevenueCat entitlement gating, the AdMob banner with a useAds context that hides ads for premium users, and the paywall screen can be wired into an existing app. The full value shows in new builds, where the required screen scaffold and config land correctly from day one.

### What stops my app from being rejected or crashing at launch, concretely?
Two specific guardrails: restore-purchases is wired into the RevenueCat entitlement flow, which App Store review checks for, and the AdMob app.json config is mandatory, which prevents the GADInvalidInitializationException crash that kills fresh installs. The onboarding-to-paywall pipeline also clears stack history so a stray back button cannot break conversion.

### Does it cover backend services, push notifications or my server API?
No. The stack is the client app: onboarding with fullscreen video, paywall, settings, RevenueCat subscriptions, AdMob, i18n and NativeTabs navigation. Your backend, push infrastructure and server-side logic are outside its scope.
