SmartBetterCities have the viewer working on an iPad but I think you need it in developer mode.
I know it's not an iPad but CityEngine webscene viewer does work on Android devices, (Chrome certainly). My Nexus 7 can just about view 3D scenes! I'd probably wait for official support or get a more powerful mobile device..
do you mean the Nexus 7 could display the webscene?
