Could you build this?
Partial A native Apple Watch and iPhone app with HealthKit workout ingestion, CRUD, and charts is vibe-codeable. Stroke detection and SWOLF/stroke-efficiency analysis from raw sensor data need signal-processing work and swim-specific validation, and open-water GPS adds more.
What it would actually take: The stack is Swift/SwiftUI with HealthKit and WatchKit, plus CoreLocation for open-water tracks. The hard part is stroke classification from wrist accelerometer and gyroscope data, which needs labeled swim sessions to validate, typically collected with a coach or swimmers. Recovery analytics and personal-best logic are simpler, but getting the stroke detection accurate enough to trust is the real barrier.
