How do I import walks from my Galaxy Watch?
Use the WandelWeb Wear app
Record your walk with the WandelWeb app on your watch. It sends the GPS route to WandelWeb through your phone. Install WandelWeb from the Play Store on your watch and make sure the phone app is open or was opened recently.
Why not Samsung Health?
Samsung Health often does not sync workouts (or not fully) to Health Connect. Even when the session arrives, the GPS route is usually missing. WandelWeb skips walks without a route because they cannot be shown on the map.
Health Connect remains useful for other apps that do share a route (for example Health Sync, Google Fit, Polar Flow, Fitbit or Coros). Connect those via Profile → Settings → Connections → Health Connect.
