RevenueCat

RevenueCat is a service that acts as the subscription and purchase backend for mobile and web apps. It takes the complex, platform-specific work of handling transactions on iOS, Android, and the web off your plate. Instead of building and maintaining separate systems for StoreKit, Google Play Billing, and web payments, you connect your app to RevenueCat's single API. It validates receipts, manages customer subscription status, and serves as a central hub for all your in-app purchase data.

What makes RevenueCat stand out is its suite of tools built on top of that core infrastructure. It offers configurable paywall templates for quickly launching purchase screens, A/B testing to optimize those paywalls for conversions, and detailed analytics to understand what drives revenue. It also automates operational tasks like handling refund requests and provides tools for customer support teams to view subscription data. The company emphasizes that its engineering team handles updates from Apple and Google, so your app stays compliant without constant developer intervention.

This tool is a major time-saver for app developers and companies of all sizes, from solo founders to large teams like VSCO and OpenAI. Engineering teams benefit by avoiding months of backend development. Product and marketing teams use it to run pricing experiments, target different user segments, and connect subscription data to their existing analytics and marketing platforms. Essentially, if your app makes money through subscriptions or one-time purchases, RevenueCat handles the plumbing so you can focus on the product itself.
