This is a Jetpack Compose project showcasing animations that are built 100% entirely with Jetpack Compose (KMP supports) to inspire your paywalls with more beautiful and engaging components, and ultimately help drive more revenue for Android and iOS. Each paywall features unique animated backgrounds and demonstrates RevenueCat SDK for in-app purchase functionality, including subscription plans and restore purchases.

This is a Kotlin Multiplatform project targeting Android, iOS.

• /composeApp is for code that will be shared across your Compose Multiplatform applications. It contains several subfolders:

  • commonMain is for code that’s common for all targets.
  • Other folders are for Kotlin code that will be compiled for only the platform indicated in the folder name. For example, if you want to use Apple’s CoreCrypto for the iOS part of your Kotlin app, the iosMain folder would be the right place for such calls. Similarly, if you want to edit the Desktop (JVM) specific part, the jvmMain folder is the appropriate location.

• /iosApp contains iOS applications. Even if you’re sharing your UI with Compose Multiplatform, you need this entry point for your iOS app. This is also where you should add SwiftUI code for your project.

Cat Paywalls KMP is built using the RevenueCat SDK for Kotlin Multiplatform to implement in-app subscriptions and a paywall system on both Android and iOS. RevenueCat handles first-party purchases across platforms, manages customer data, supports A/B testing, and provides source-of-truth analytics.

• Turn Your App into Revenue: Building Paywalls in Android With Jetpack Compose: In-app subscriptions have become a popular way to monetize mobile applications that offer recurring value to users. In this article, you'll learn how to seamlessly implement in-app subscriptions and paywall features in Android using Jetpack Compose and the RevenueCat SDK.
• How to monetize Android apps with ad-free subscriptions using RevenueCat: Most apps monetize through ads using things like AdMob or Audience Network. To maximize your earnings with ads, you need to show as many of them as possible, which makes for a pretty lousy user experience.
• Server-driven UI SDK on Android: how RevenueCat enables remote paywalls without app updates: In this article, we'll explore the concept of server-driven UI, with a focus on how RevenueCat's Paywall Editor enables you to build and remotely update paywalls—without needing app updates—using RevenueCat's Android SDK.
• Simplify in-app purchase unit testing with RevenueCat’s Test Store: In-app purchase testing has long been a pain point in Android development. Setting up Google Play sandbox environments, managing test accounts, waiting for purchase verification, dealing with cached state… the friction is real. Luckily, RevenueCat’s Test Store is a solution to this problem — offering instant testing without the complexity of real billing systems. But the real benefit of Test Store isn’t just its simplified setup, it’s how it enables true unit testing of purchase flows, with minimal infrastructure.
