Apple Watch HRV Wellness App

I’m building a wellness-focused Apple Watch app that centres on real-time Heart Rate Variability (HRV) monitoring. Using HealthKit, the Watch should stream HRV data continuously, display it in an easy-to-read interface, and keep everything running smoothly without draining the battery.

Core scope
• Establish a reliable HealthKit pipeline that captures HRV in real time on watchOS.
• Design a lightweight Watch interface that shows live HRV, trend arrows, and an at-a-glance colour cue for balance vs. stress.
• Implement optional silent haptic or visual alerts when HRV falls outside a configurable threshold.
• Ensure data syncs back to the user’s iPhone Health app automatically.

Acceptance criteria
1. Live HRV reading refreshes at HealthKit’s permitted frequency with no crashes during a 30-minute test session.
2. UI remains responsive while streaming; battery impact stays within Apple’s recommended limits for background sessions.
3. HRV values recorded by the Watch are visible in the iPhone Health app within one minute of capture.
4. Xcode project delivered in Swift/SwiftUI (no storyboards) and builds cleanly on the latest public Xcode and watchOS SDK.

If you’ve shipped watchOS apps that lean on HealthKit before, especially anything dealing with live heart data, you’ll feel right at home. Send over a brief note about similar work and a TestFlight build or video demo if available; I’ll share design mock-ups and the rest of the product roadmap once we confirm fit.
