Here are examples of images that normally appear with a Web App export from InDesign and in5.

E.g., for a non-mobile device:

E.g., install screen on an iPad to install to the Home Screen.

Removing the device limitations

If you don't want the Web App to be limited to mobile devices, and/or you'd like to remove the instructions screen, the following bit of custom code changes the output so that image of instructions doesn't appear and the page simply loads as a web page (but still allows the Web App installation on supported devices).

Removing all limitations and install instructions

Alternatively, if you use the Presentation Mode panel (in5 > Enhancements), you can turn on the Save to Home Screen feature without using any of the install screens shown above.

Temporarily test Web Apps as web pages

Alternatively, if you want to temporarily bypass the install screens (on any device) and treat the content like a web page (instead of a WebApp), you add ?webapp=0 to the end of the URL (e.g.,
