Saving a mobile prototype directly to your phone can give the appearance of actually launching an app, further immersing users into the design experience. If you have an iPhone, the process of saving a mobile prototype to your device is simple.
Note: These steps apply specifically to standard prototypes. Currently, you cannot save a Studio prototype to your iOS device. You can, of course, view a Studio prototype on your phone, as described in the "Mirroring Studio Prototypes" section of this article from our Getting Started Guide: Introduction to the InVision iOS App
Setting the icon
With InVision you can choose what image will appear as the prototype icon. We recommend setting this image first, or it may not appear when you save the prototype to your device's home screen.
