It’s not that it’s so ugly it makes some people want to vomit, that’s a whole different discussion. Some users have complained on [Apple's forum] of nausea due to the zoom animations that cause a slight parallax effect. The post has more than 280 replies so far with many complaining having the same side-effects.
I guess Apple didn’t test the iOS7 with enough people to detect this problem before release, either that or they just don’t care.
Below are some comments from users:
“I thought I was going crazy today after I updated my phone and I noticed I was feeling queasy every time I used it. Now I see I am not alone! I just used my phone for about 20 minutes and now I feel like I’m going to vomit. There has to be a way to turn this off!”
“I went to the Apple store, I spoke to customer service, I even went as far as thinking about buying a Blackberry! It’s making me so dizzy! I just took all my apps and put them all in folders and only left my text message app and then on the bottom you are allowed four apps, put important ones there. Move all other apps to another page and this way you don’t have that 3D effect going on because there are no apps on your main page that move when you open and close. UGH! Thanks a lot APPLE!! How did none of the testers get sick?!”
“So today has been a total wash. I had to go home “sick” from work because of the intense nausea due to using my iphone with iOS 7.
Again, for me it’s not just the zooming that makes me sick (although it does aggravate the nausea even more) but just using the interface as usual i.e. reading texts, e-mail, switching apps, etc. makes me terribly and uncomfortabley ill after a minute or two.
This is unacceptable as I use my phone a lot throughout the day.”
“+1 for dizziness and nausea here, too. Called support earlier today and they told me it couldn’t be turned off – the rep I spoke with was very pleasant, but didn’t get anywhere with it. A “Classic Animations” option would be fantastic!
I’ve been having no luck downgrading, either. Seriously disappointed – I don’t want to go back to my old Blackberry brick, but if it’s that or constant nausea“
