Hello, I will translate your polished web app into a native iOS experience for iPhone and iPad, keeping the layout, visuals, and user flow instantly recognizable while delivering smooth animations, responsive constraints, and standard iOS navigation. I’ll pick Swift for a fully native build, or a hybrid approach if you prefer, and I’ll wire your REST/JSON endpoints securely, adding robust error handling and retries. Clear milestones with testable builds and regular updates will guide the project, and I’ll work closely with your backend team to align API contracts, latency targets, and error states. The result is a high-quality app that sails through App Store review and feels native across devices. Do you prefer native Swift or hybrid, and any constraints I should consider? Which iOS versions and devices should we target, and is iPadOS a must? How should error states be handled for API calls (retry logic, user feedback, offline mode)? What authentication or session management is required and how should credentials be stored securely? What milestones, delivery cadence, and acceptance criteria do you expect for progress updates and testable builds? Best regards,

What I’ll deliver: • Native iOS app (Swift or high-quality hybrid, aligned with App Store guidelines) • Faithful adaptation of your existing UI/UX with native navigation patterns • Clean integration with your REST/JSON AI endpoints • Robust error handling, loading states, and edge-case management • Optimized layouts for multiple screen sizes (iPhone + iPad) • Smooth animations and transitions consistent with iOS Human Interface Guidelines • TestFlight builds at each milestone for review • Final App Store–ready build with submission support I’ve converted front-end only web products into native mobile apps before, ensuring design continuity while delivering the performance and polish Apple expects. I’m comfortable collaborating closely with backend teams and working from existing UI references to avoid rework.
