When you select Apple Health as your source for your StepBet game, only steps taken with your phone/Apple Watch and tracked directly via the Apple Health app will count towards your game. Any additional sources (Fitbit, Garmin, Pedometer app, Stepz, Sync Solver, etc.) will not count towards your StepBet game.
