The operating system includes more animation than the previous version. Apps zoom open and closed. Some people have said the movement gives them motion sickness.
"I'm now going on day 3 of total nausea. At first I didn't want to believe it's because of iOS 7, but I can't stand even looking at non animation areas for more than a few minutes even typing this," wrote one commenter on an Apple message board.
Resorted to closing my eyes or covering my hand over the screen between every zoom in/out animation for ios7 so I don’t get motion sick.— Jenni Leder (@thoughtbrain) September 23, 2013
"I had severe vertigo the minute I started using my ipad with ios 7. Lost the rest of the day to it... And not happy at all. It's the transition between the apps flying in and out. I can use it now limited time, AND ONLY if I close my eyes between apps," another wrote.
iOS7 makes me motion sick just using my phone hahaha that's something to cry about— McKeηηa Stoddard (@McKennaStoddard) September 18, 2013
There is a solution to tone down the animation through iPhone settings, but not turn them off fully, leaving some users left to downgrade to iOS 6.
If you get sick of the iOS7 parallax motion: Settings > General > Accessibility > Reduce Motion— Will Henderson (@willhenderson) September 18, 2013
Users on Twitter have been skeptical about the sickness.
