Goose Swift is a local-first iOS companion project for WHOOP 5.0 devices. It is currently an alpha proof of concept intended for developers who can build the Swift app and Rust core themselves. The app connects to WHOOP 5.0 bands through Bluetooth and routes device data through a local Rust processing layer. It turns available signals into health, recovery, sleep, strain, stress, cardio, energy, coach, and debug views. The project includes a SwiftUI app, a Rust bridge, HealthKit support, a workout Live Activity extension, and internal documentation for its MVP pipeline. It is best understood as an experimental, independent wearable-data project rather than a finished consumer health tracker.
