Information For App Developers

iOS devices are used by a significant number of vision impaired people. This is mostly due to Apple’s VoiceOver program which is included on all current iPhones, iPads and iPod Touchs.

VoiceOver enables the user to interact with the device without the need to see what is on the screen. Apple have provided some information as to how VoiceOver works for the end user at www.apple.com/accessibility/iphone/vision.html.

As a developer, there are a number of things that you can do to make your app more accessible to users of VoiceOver. Apple have provided a guide for developers on how to make their applications accessible at http://developer.apple.com/iphone/library/documentation/UserExperience/Conceptual/iPhoneAccessibility/Introduc....
