Postnatal Exercise iOS App Build

I have the full UI design, detailed exercise instructions, and a library of demonstration videos ready to go; now I need them assembled into a production-ready iOS application. All workouts are grouped by postnatal week, and I want users to create an account with a simple e-mail/password flow before they reach the dashboard.

Core experience
• Each week unlocks its own set of video tutorials and written cues.
• Exercise tracking records reps, sets, or completed follow-along sessions and feeds a lightweight progress report so users can see improvements over time.
• A summary screen lets new mums spot any skipped weeks and jump back in easily.

Scope of work
– Build the app in Swift (latest stable Xcode) using my Figma screens and supplied MP4s.
– Integrate secure e-mail/password authentication (Firebase Auth or a comparable Apple-approved library).
– Implement local or iCloud-synced data storage for progress and tracking.
– Handle all privacy, health-disclaimer, and App Store nutrition labeling that Apple now requires for fitness content.
– Test on current iPhone devices and the latest iOS version, fix any crashes or layout issues, then submit through my Apple Developer account.
– On approval, hand over the full Xcode project, assets, and build notes.

Please share links to at least one iOS app you have shipped that is visible on the App Store, along with your fixed price and the timeframe you need to reach submission. I am funding this myself, so realistic, cost-conscious proposals are appreciated.
