    Goose Swift

    Goose Swift

    Goose Swift proof-of-concept README

    ...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.

  • PRTG Catches Network Issues Before They Cause Downtime Icon
    PRTG Catches Network Issues Before They Cause Downtime

    Threshold-based alerts flag problems early, so your team can act before users notice, not after.

    Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.
