How can I connect or disconnect the eBike Flow app with the Apple Watch?
On your iPhone, go to the Watch > My Watch > Available Apps > Flow app and select Install. The app now appears under Installed on Apple Watch and Show app on Apple Watch is selected.
Then go to Settings > Connected services > Apple Watch > Integrate heart rate in your eBike Flow app. Now you have to allow the Flow app to access the training and heart rate data from your Health app. Back in the settings of your eBike Flow app, you can now activate Start Watch app automatically under Apple Watch. Your heart rate will then be automatically tracked on every ride.
On your iPhone, go to the app Watch > My Watch > Installed on Apple Watch > Flow and uncheck Show app on Apple Watch.
