At Quizlet we're deeply committed to providing powerful and free learning tools to students everywhere, including those with special needs.
VoiceOver is an advanced screen-reading technology from Apple that lets students hear what's onscreen and control their keyboard without visuals. So even if a student is vision-impaired they can still use the Quizlet app.
To enable VoiceOver on your iPhone or iPod, click on Settings -> General -> Accessibility -> VoiceOver
PS. Special thanks to iPhone-toting Quizlet user "Pumkey" who first recommended we support VoiceOver. We deeply appreciate feedback like this. Even though a 1-star iTunes review stings a bit at first, it's passionate users like this who help us continuously improve Quizlet :)
