In order to use “screen mirroring” to view your app on a larger TV screen, it requires both an iPhone and an Apple TV. You can select the screen mirroring option on your iPhone by swiping up from the very bottom of your main screen which will pull up the control centre menu. For some newer iPhone models, you may have to swipe on your main screen from top to bottom. From the control centre view, you can then select “Screen Mirroring” which will connect to your Apple TV. After that, you can open the app and continue with your workouts!
