RevenueCat helps you sell subscriptions and one-time purchases in your Rey app. It connects your app to Apple, Google, and web billing, then keeps track of customer access, receipts, offerings, and revenue in one place.

​
What RevenueCat is for

Use RevenueCat to:
  • Sell subscriptions, trials, and one-time purchases.
  • Show paywalls and determine which customers have access to premium features.
  • Validate purchases and keep entitlement status in sync across supported platforms.
  • Manage products, offerings, pricing experiments, and revenue reporting from its dashboard.
Rey uses RevenueCat’s SDK keys to connect your app to the right RevenueCat project. Your secret API key is stored securely by Rey and is used for purchase and entitlement management; it is never included in your published app.

​
Before you begin

You will need a RevenueCat project and at least one platform app registered in it. Follow the setup guide next, then connect the API keys to Rey.
