RevenueCat

RevenueCat simplifies implementation and maintenance, manages customer subscription status, and aims to solve painful edge cases. As a single source of truth for customer purchase data across every platform, RevenueCat provides out-of-the-box metrics and charts so the user can gain a deeper understanding of revenue, retention, and churn. Filters and segments enable users to compare performance of specific attributes like monthly vs. annual subscriptions. And reporting dashboards are real-time.

The RevenueCat dashboard lets the user view basic customer information, including a timeline of their purchases, and allows users to grant promotional subscriptions. This can be used to debug issues and deliver help with customer support.
