Tiles view on Safari (left) vs Tiles view launched from home screen icon (right)
You can get a full screen view of your data on mobile (iOS) by adding an icon to your home screen to launch your Initial State application. The top and bottom Safari menu bars are removed in this mode. See this article for instructions on adding an icon to your home screen in iOS.
The top timeline toolbar can be hidden by clicking on the arrow icon in the center of the timeline. This will give you more screen space for your dashboard. See this article for more information on hiding your timeline.
