RevenueCat

A subscription backend for phone apps: its SDK runs in-app purchases through Apple and Google, its server records which users have paid, and its dashboard reports the revenue.

What RevenueCat is

Written from its maker's own pages, read on 13 October 2026.

RevenueCat is a subscription backend for apps, made by the company RevenueCat. A subscription backend is the server side of in-app purchases: it records which customer bought which product and whether each subscription is still active. RevenueCat covers purchases on iOS, Android, smart TVs and the web.

A developer adds RevenueCat's open-source SDK (software development kit, a library built into the app) to each app. Purchases still go through the app stores, and RevenueCat validates the store receipts automatically for StoreKit (Apple), Google Play, smart TV and web, then keeps one subscription record per customer across platforms. A REST API and webhooks (HTTP calls sent to the developer's server when an event happens) pass these events on. A paywall editor with templates builds the purchase screen, and A/B tests compare paywalls and prices. A dashboard reports more than 40 metrics, and integrations send purchase data to marketing and analytics tools.

RevenueCat is a hosted service. It is free up to a monthly limit of tracked revenue and then takes a percentage of the revenue it tracks; large apps get custom Enterprise pricing.

Made by: RevenueCat
Price: 1% of the revenue it tracks, charged only in months with US$2,500 or more of tracked revenue (read 13 October 2026)
