Project description:
"I need a React Native developer who can extend an existing mobile code-base with a dedicated Apple Watch companion focused on health and fitness. The watch app should:

• Track heart-rate in real-time, log step counts, and record workout sessions accurately through HealthKit
• Present that data in a bright, colourful, easy-to-read interface that feels energetic rather than clinical
• Sync seamlessly with the main iOS app, storing every metric locally first and then pushing it to the cloud the moment a data connection is available

If you have already shipped Apple Watch experiences, especially ones using React Native bridges or native watchOS extensions, please send over a link, TestFlight invite, or short video so I can gauge code quality and UI polish.

Once I review your past work I’ll share the full user flows, assets, and API details. The final deliverable will be the complete Xcode / React Native project with watchOS target, ready for App Store submission, plus brief setup documentation so my team can run it locally.

Looking forward to seeing what you’ve built." (client-provided description)
