Activity upload integration in development.
Built on the Web Bluetooth API to support the standard GATT Heart Rate Profile. Connects directly to any compliant hardware—including monitors from Polar, Garmin, and Wahoo—without proprietary hubs or native drivers.
Integrated via the Spotify Web Playback SDK. Playback state is tightly coupled to your workout timer: music automatically starts when you begin training and pauses when you stop, removing the need for manual DJing.
We are currently building secure OAuth integration to upload your workout summaries directly to Strava.
Pending API Approval.
Pair your Bluetooth heart rate monitor securely via the browser.
Link your Spotify Premium account to control playback with your workout.
