jump up the severity of the jump from ios 6 to ios 7 means some organisations dealing with such motion - sickness problems are recommending that people with such conditions do n't upgrade their ios devices . tap an app and it 's making people sick . the introduction of fake zooms , parallax , sliding and other changes in apple 's new iphone and ipad software has a very real effect on people with vestibular disorders apple 's new mobile operating system for the iphone and ipad , ios 7 , is stark and minimal , yet dynamic . the same minimal effect is true of stock android and windows phone , which lack triggering animations and effects as dynamic and aggressive as those in ios 7 . a major change in apple ’s ios 7 update was its sleek , minimal aesthetic ; however , the amount of motion now found within is anything but minimal . the screen zooms in and out as folders and apps are open and closed ; the app switcher zooms and slides ; full - screen slide transitions are commonplace ; and a faux-3d parallax effect exists on home screens , with icons appearing to float and move independently of background wallpaper . for many people ( most of stuff included ) , this might seem dynamic and exciting . a number of affected users have reportedly switched iphones that had already been upgraded to ios 7 for models running ios 6 . it makes frequent use of zoom and slide animations ; the home screen boasts parallax , with icons apparently floating above subtly animating wallpaper .
