Building & Monetizing Cross-Platform Apps with React Native

In this talk, I’ll walk you through building and monetizing a cross-platform wallpaper app using React Native, Expo, Stripe, and React Native Purchases. The goal is to show how easy it is to create an app that works on iOS, Android, and the web—and start making money from it.

I’ll start by discussing why React Native is a good choice for multi-platform development, highlighting how Expo simplifies the process and what makes the ecosystem developer-friendly. From there, I’ll dive into monetization strategies, breaking down how in-app purchases and subscriptions work across different platforms. Since iOS, Android, and the web all have unique approaches to handling payments, I’ll cover the key differences and challenges, along with how tools like Stripe and RevenueCat (React Native Purchases) can streamline the process.

The core of the talk is a 15-minute live coding session, where I’ll build a simple wallpaper app from scratch using React Native and Expo, then integrate subscriptions using React Native Purchases and Stripe. By the end of the demo, the app will be set up to generate revenue across multiple platforms.

I wrap up by covering some practical considerations for deployment and launch—including setting up payments in the App Store, Google Play, and Stripe, dealing with potential app rejections etc.

By the end of the session, you’ll see how React Native makes multi-platform monetization more accessible than ever. You’ll leave with practical knowledge on building, monetizing, and launching a cross-platform app.
