Unfortunately Samsung won't currently allow us to sync steps from the Samsung Health app. For Samsung Heath and Samsung Galaxy Watch users, our recommendation is to manually add your distance. We know this isn't ideal and we're sorry for any inconvenience it may cause.
At the end of each day (or every few days), just login to Big Team Challenge and type in your tracked activity in steps, miles, kilometres on the Dashboard page.
You can also manually enter these distances on our iOS and Android apps.
