I already run a fully-functional website and now want it packaged into polished native apps for both iOS and Android. The look, navigation flow, and existing back-end logic should carry over seamlessly, but with the responsiveness and smooth interactions users expect on mobile. The single must-have feature is a secure, fully tested payment gateway. Whichever stack you prefer—Swift + Kotlin, React Native, Flutter, or another proven toolset—is fine as long as the end result is accepted by the App Store and Google Play without red-flags and the payment flow passes their review guidelines. Deliverables: • iOS and Android builds ready for store submission • Payment gateway integrated and sandbox-tested end-to-end • Source code and concise setup/build instructions I can provide the current site’s APIs, design assets, and access to our payment provider account as soon as we kick off. Let me know your framework of choice, a rough timeline, and any recent apps you’ve shipped that included in-app payments.
