Screen Size
If you’re in a pinch, you can totally use your iPhone during your lesson. But that is less from ideal since your screen is so small! The bigger your screen, the easier it will be to see during your lesson.
If you are using an external webcam like the Logitech C920 (which works with Windows and Mac computers—unfortunately not with iPads), you can get even more creative about where you place the camera and what screen you use. It’s possible even to use your TV as a screen for your lesson!

The goal is to make it as easy as possible for you to see the screen clearly for the most effective lessons!
