RevenueCat generates events for every useful subscription event:
Integrations deliver those events to where you need them, how you want them.
Events are delivered even if users don't open your app. This allows you to truely understand your subscription business — independent of in-app events.
RevenueCat receives Apple or Android in-app purchase tokens, associates them with a user record, and ensures that it is tracked and kept up to date. The data is de-duplicated, prices are computed, and a reliable picture of subscribers and revenue is created.
