What is RevenueCat

RevenueCat allows you to add in-app subscriptions to your native mobile app. To get started, ask Agent to set up a subscription, connect your RevenueCat account, and Agent handles the logic and provides a test environment.

​
Prerequisites

Before you start, you need:
  • A Replit project created with a Mobile app
  • A RevenueCat account (only an email and password are required—no bank account or additional setup needed)

​

Ask Agent to add a subscription

​
Test subscriptions

Replit previews use RevenueCat’s test mode. When you test a purchase in Expo Go, you see a test purchase dialog instead of a real payment flow. No money is charged.

Test purchases are safe to use during development. You can test both successful and failed purchase flows without any real charges.
Once your app is published to the App Store, purchases use real money. Make sure your RevenueCat products and pricing are correct before submitting to the App Store.

​
Manage subscriptions

To modify your subscription, ask Agent. For example: Agent updates your RevenueCat product configuration, paywall UI, and subscription logic to reflect the change.

Syncing to App Store Connect

For in-app purchases to work in TestFlight and the Apple App Store, you’ll need to agree to Apple’s Paid Apps Agreement and connect your bank account. This is done through App Store Connect. You’ll need a paid Apple Developer Account. This is required if you want to publish your app to the App Store. Afterwards, you can sync your in-app purchases configurations from RevenueCat to App Store Connect directly through Replit.
