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.
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.
These steps apply specifically to standard prototypes. Currently, you cannot set an icon for Studio prototypes.
To set the icon:
Sign in to InVision and open your prototype.
Hover over the icon next to the prototype name, and click the + button to add an image.
Select any image from your computer that is 120 x 120 pixels.
Your prototype icon should now be set.
Adding a prototype to your iPhone
To add a mobile prototype to your iPhone:
After creating a share link for your mobile prototype, open your iPhone and paste that share link into the Safari web browser.
Tap the Share icon () and choose Add to Home Screen.
Enter a name, and click Add.
The prototype share link should now appear as an app icon on your home screen. Click the icon to launch the prototype.
