iOS & Android App With Purchases

I’m moving ahead with a mobile app that will launch simultaneously on iOS and Android, and its core revenue driver will be in-app purchases. The vision is straightforward: a polished, store-ready product that lets users buy digital content or subscriptions seamlessly while Apple’s StoreKit and Google Play Billing work reliably behind the scenes. To keep the codebase efficient I’m open to a shared framework such as Flutter or React Native, though I have no objection to fully native builds if you can demonstrate faster approval times or smoother performance. Whichever route you choose, the purchasing flow must be secure, receipt-validated, and easy for me to extend with new items later. Key deliverables • Complete, compilable source code for both platforms • Fully implemented in-app purchase flows (consumables, non-consumables or subscriptions as needed) with sandbox testing evidence • Receipt / purchase validation and graceful error handling • A brief deployment guide outlining certificates, provisioning, and store-listing steps Once these items are met and test transactions clear on both stores, we’re done. Let’s keep communication tight so the build ships quickly and passes review on the first attempt.
