Hello there, I have worked on several React Native iOS apps where I handled bug fixing, performance optimization, and integration of in-app purchase systems like RevenueCat. I can debug and resolve the functional errors in your app, improve performance, and ensure smooth integration of subscriptions and in-app purchases so everything works seamlessly for your users. My suggestion is to first run a detailed code and performance audit to identify all underlying issues before integrating RevenueCat. This ensures we’re building on a stable foundation and prevents future errors. After that, I can set up and configure RevenueCat, handle sandbox testing for both purchases and subscriptions, and make sure the workflows are fully functional in production. Could you confirm if your app already has any partial RevenueCat setup or if we’ll be starting its integration from scratch? Best regards, Aliza K.
