Every iOS developer should read this. It’s long, so feel free to save it for later. But really, read it.
VoiceOver accessibility in iOS is extremely easy. I made dramatic improvements to Instapaper’s accessibility with about 15 minutes of effort a few versions ago. Instapaper is already often used by people with reduced vision because it can show web-page contents with large, adjustable fonts. It’s a no-brainer to also include support for those with very low or no vision.
And this article just taught, inspired, and reminded me that there’s still more I need to do (for instance, applying the “Updates frequently” attribute to the update-status label). It probably needs another 30 minutes of effort. That’s nothing.
Excellent VoiceOver UI is extremely little effort that yields massive improvements for many people.
