## What it is
RevenueCat's open-source client SDKs (purchases-ios, react-native-purchases) that wrap StoreKit and Google Play Billing to simplify implementing in-app purchases and subscriptions. They pair with RevenueCat's hosted backend for server-side receipt validation, entitlement management, paywalls, and subscription analytics.

## Use cases
- add in-app subscriptions to an iOS app without managing StoreKit edge cases
- validate receipts server-side and track subscription status across platforms
- build and A/B test paywalls remotely without app updates
- sync purchase events to analytics and attribution tools like Amplitude or AppsFlyer
- migrate existing subscribers to a unified cross-platform subscription backend
- grant promotional subscriptions and view customer purchase history

## When to choose
- you're building a mobile app with subscriptions or one-time in-app purchases on iOS, Android, or cross-platform frameworks
- you want a hosted subscription backend instead of writing your own receipt validation
- you need paywalls, experiments, and subscription analytics out of the box
- you want free usage up to $2,500 monthly tracked revenue

## When to avoid
- you need fully self-hosted billing with no third-party dependency or hosted service
- your app has no monetization or only sells physical goods outside app stores
- you can't accept RevenueCat's pricing model of 1% of tracked revenue above the free tier
- you only need a thin StoreKit 2 wrapper and don't want a backend service
