I’d begin by mapping the existing Sports Performance Hub web app’s soccer-player workflows and API responses, then reproduce those flows as an iOS client rather than redesigning the product from scratch. The goal is a TestFlight-ready iPhone build covering the web app’s current functionality, with the third-party API integrations connected and the interface adapted to iOS navigation, spacing, forms, and touch behavior. I’ll use Swift with a maintainable feature structure, first wiring authentication and core data flows, then implementing the player performance screens and API-dependent actions. I’m comfortable signing the NDA and required legal documents before receiving protected app or integration details. You’ll receive the working iOS build and source implementation in 7 days, assuming access is available promptly. Will the web app URL and third-party API documentation be available immediately after the NDA is signed? Muhammad Saad

Matching every web feature in iOS is mostly about parity, API behavior, and native interaction details. I’d start with a feature-by-feature audit of the Sports Performance Hub, then map the existing API integrations and iOS-specific UI changes before building. A relevant shipped example is ChurchSync, an iOS and Android app live in both stores using a Capacitor wrapper with RevenueCat subscriptions. I’m ready to sign the NDA and other legal documents before reviewing the full scope. The first milestone can be the parity audit plus one working end-to-end app flow, so you can verify the direction before the full build.

Hello, I can convert your existing Sports Performance Hub web application into a polished, fully native iOS app while preserving its existing functionality and adapting the experience to proper iOS design standards. I’ll first review the web application, existing workflows, APIs, and technical documentation to understand what has already been completed and avoid duplicating unnecessary work. **Approach:** • Native Swift/SwiftUI iOS architecture • Replicate all essential web-app functionality • REST/API integrations with your existing third-party services • Secure authentication and data handling • iOS-native navigation, layouts, forms, and responsive UI • Push notifications and device-specific capabilities where required • Proper loading, error, offline, and empty states • Testing across current iPhone/iOS versions Since the majority of the backend and functionality is already available, I can focus development on efficiently translating the existing platform into a reliable mobile experience. I’m comfortable working under NDA and following your legal/documentation requirements before accessing confidential materials. **Deliverables:** Complete Xcode project/source code, integrated APIs, TestFlight build, documentation, and final production-ready iOS build. I can share relevant examples of my previous iOS applications and API-driven projects upon request. I’m ready to review the existing web app and provide a clear timeline and development plan.
