Let's be honest, online tools these days generally fall into two categories: too cheap for big companies, or too expansive for small startups. RevenueCat scales with your company, and that's really what I appreciate the most. You can start small, scale, and still use their products once you've generated more revenues. The interface is very well made, and they even have webhooks!

RevenueCat makes subscription management incredibly simple. The SDK is easy to integrate, documentation is clear, and it saves a lot of time handling receipts, renewals, and edge cases across App Store and Play Store. Analytics and webhook support are also very reliable.

The documentation for hooking up the service is clear and to-the-point. And the integrations just work.
