Form Engine form links work on any mobile device browser just like on desktop. Mobile users will not be able to print/save the pdf of the forms they submit since there is no file storage on smart phones, but their documents can be emailed to them using notifications in Quickbase.
How to change Template Size
The default size for Templates is 8x11.5 (Letter), but Builders have the ability to change this. One of the options available is 3.8x5 (Mobile). To make this change click on the "Set Page Styles" icon in the toolbar.
From the Page Preset dropdown, select Mobile then click Apply.
Make sure to Save the changes to the Template before moving forward.
