Polar Flow update – New way to manage favorites
Polar Flow web service has a refreshed favorites page to organize your training targets, routes and Strava segments.
You can manage the favorites for each Polar device you have registered on your Polar account. Just click on the favorites star icon on top of the page at flow.polar.com. Choose your device on the drop down list on the right side of the page and manage device-specific targets, make changes on the left and sync your device when you're done.
