Hopefully there's a simple explanation for this... Just upgraded to an iPhone 6 and set up the phone from an iCloud backup. All worked great! Decided to reorganise my apps and move them around. So made them all 'wobbly' and started moving. One app just disappeared when I touched it. Have I somehow hidden it?? I haven't deleted it. I can find and launch the app using spotlight search. When I close it, it zooms away and disappears.... to where? Anyone know??
