The real secrets of iOS and accessibility – Six Colors:

There’s a joke I tell a lot: if you encounter an article whose headline includes the words “secret features” and “iOS”, chances are you’re about to be taken on a whirlwind tour of your phone’s accessibility settings. “Did you know you could….?” Or. “Buried deep in iOS settings, you’ll find…”

Truth is, these aren’t secret features at all; they’re just unfamiliar to people whose eyes, ears and hands operate in a typical way. And these “secrets” are rarely written about, even in comprehensive coverage of iOS. “Invisible” might be a more honest way to describe these tools.

Apple’s products make Accessibility a first-class feature, though often below the bar of easy discoverability.
