I’m ready to turn a clear idea into a fully functioning mobile app that ships on both the App Store and Google Play. The core requirement is a smooth, secure in-app purchase flow—think consumables, non-consumables, or subscriptions—implemented to Apple and Google guidelines so the app passes review the first time. I’m flexible on tech. If a cross-platform stack such as Flutter or React Native keeps maintenance lean, great; if you prefer native Swift/SwiftUI and Kotlin, that works too—as long as the codebase is clean, well-documented, and test-driven. A typical user journey will start at a simple onboarding screen, move to gated content, and then prompt the user to unlock premium features through purchases. You’ll help fine-tune that flow, wire up sandbox testing, and make sure receipts are validated server-side or through a secure fallback you recommend. Deliverables • Working iOS and Android builds ready for TestFlight and Internal Testing • Fully implemented in-app purchase modules with sandbox test cases documented • Source code pushed to a private Git repo, accompanied by setup instructions and basic unit tests • App Store and Google Play store-listing assets (screenshots, short description) or, at minimum, guidance on generating them Let me know which framework you’d pick, any similar projects you’ve launched, and an estimated timeline for an MVP submission.
