What's the Best Payment Platform for Subscription Services in My Mobile App?

I've had a great experience with Stripe for handling subscription payments. It's particularly strong for cross-platform support, and integrating it with React Native is straightforward through packages like `tipsi-stripe` or `react-native-stripe-sdk`. If your app is built with Flutter, you can also use `flutter_stripe`. They take care of a lot of the difficult parts of subscriptions, taxes, and invoicing, plus they scale well if you're planning to go global. Don't forget to also consider in-app purchases for iOS/Android for a smoother user experience!
