I am visually impaired and can get around pretty well in iOS6. I almost fell over when I saw how illegible the fonts are in iOS7. All of the glitzy articles, screen shots, and demos never really showed how bad and illegible the fonts were. They were always clear and bright. Not what they are on the actual device. The design is beautiful, but the function *****.
I was freaking out trying every setting I could, and searching on line what I could do. I finally found out how to downgrade my phone back to iOS6. Just the horrible keyboard was enough to make me run screaming. I couldn't make out ANY of the letters! Bold & contrast settings - didn't matter.
iOS 7 made my device unusable. They have to make the change to something more legible. It seems like they never had a group of beta testers that has accessibility issues let alone an aging population. I have had a few relatives with good vision say it is really hard to read.
I'd be happy to beta test for them. But unit they they make changes to the legibility of the whole system font, I will unfortunately have to stay with iOS6...
I know it is early in the design, and I can see where they are going with this and it will be great, but to leave a LOT of users scrambling to just get around their devices, visually impaired or not, is a real disappointment. I am an Apple fan, and I really feel let down. 😟
I hope there is an update SOON!
