Expo Go limitations

Purchases do not work in standard Expo Go. The RevenueCat SDK and SecureStore (used for credential storage) are not available in Expo Go.
To test real purchases, you need either:
  • A custom dev build (npx expo prebuild then build for your device)
  • A production build (through app store or ad-hoc distribution)

​
Test vs production API keys

Newly automatically manages two sets of API keys: You don’t need to manage this manually. The app automatically uses test keys in development and real keys in production. The switching happens at runtime based on React Native’s __DEV__ flag.

​
Web preview

You can preview your paywall in the web browser. Here’s how it works:
  • Pricing is real — mock data is fetched from your RevenueCat dashboard so prices shown match your actual product configuration
  • Purchases are simulated — no real charges occur in web preview
  • Purchases persist — test purchases persist across page reloads so you can test the full flow
Web preview is great for testing your paywall UI and flow. For testing actual purchase mechanics, use a dev build or production build on a real device.

​
Testing checklist

1

Test in web preview first

Verify the paywall looks correct and the flow works end-to-end.
2

Build a dev build

Run npx expo prebuild and build for your device to test with Test Store keys.
3

Test on a real device

Use Apple’s sandbox testing or Google Play’s test tracks for real purchase flows.
