As someone that has created several in-app subscription apps, I am interested in your approach. We currently use RevenueCat so familiar with the challenge your are tackling.
When will you publish your SDK specs? Beyond native code (SwiftUI and Kotlin), will you also support React Native and other languages as well? Finally, are you incorporating in PayWall page design for A/B testing messages and offers for signup?
I know you are early in the process and any development details you can share would be appreciated.
