Compose Multiplatform subscriptions: single codebase for iOS and Android

The text details how the RevenueCat KMP SDK streamlines cross-platform subscription management in mobile apps by eliminating the need for duplicated code across Android and iOS platforms. By utilizing Kotlin Multiplatform, developers can write subscription logic once and apply it to both platforms, with the SDK automatically handling the integration with Google Play Billing and StoreKit. The article guides users through setting up a Kotlin Multiplatform project, configuring the RevenueCat dashboard, and integrating the SDK to manage premium content, run in-app purchases, and utilize a server-driven paywall. The SDK simplifies subscription management by abstracting concepts like offerings, packages, entitlements, and customer information, allowing developers to focus on product differentiation and experimentation without the overhead of managing distinct platform-specific implementations.
