RevenueCat

RevenueCat operates backend infrastructure that handles in-app subscription management for app developers across iOS, Android, smart TV, and web platforms. Instead of dealing with the technical complexity of different app stores themselves, teams can focus on their core product.

The platform functions as a "subscription backend-in-a-box": it automates receipt validation across multiple app stores and simplifies the technical implementation of purchases. RevenueCat centrally handles store-specific changes and maintenance, so development teams don't have to deal with every platform update individually. Core features include pre-built paywall templates with A/B testing, campaign analytics and audience segmentation, unified subscription data, automated refund handling, and retention tools.

According to the company, RevenueCat supports more than 147,000 apps that together process $17 billion in annual revenue and generate 5 billion API requests daily - including well-known apps such as ChatGPT, VSCO, and Photoroom.

The business model is freemium: full feature access is free until an app reaches $2,500 in monthly tracked subscription revenue; billing beyond that scales with processed subscription volume.

RevenueCat was founded in 2018 and has since become one of the most widely used tools for mobile subscription apps, precisely because App Store and Play Store billing logic is too complex for many smaller teams to implement entirely on their own.
