Mobile Accessibility Testing Guide for Android and iOS – free

Posted on Thursday, 2 November 2017 by Henny Swan

The TPG Mobile Accessibility Testing for Android and iOS (PDF, 2.6MB) is a free accessible PDF outlining how to test native apps and the web for accessibility on Android and iOS. It provides an overview of accessibility settings, how to use them and common testing tools.

Instructions on how to test content are provided for Android Talkback, iOS VoiceOver, zoom and switch settings. Also included are some testing tips, differences between testing mobile web and native apps, as well as an explanation of gestures and how to use them.

This is a great document to use if you are testing, developing or designing apps and need to understand how accessible your content is and how usable it is for people of different abilities.

Additionally, Android features can be inconsistent across devices and versions. The document flags issues where known, however, there may be further issues.

  1. Hello Henny,

    similar to Mohiths, why was this published as a PDF at all? I’m professionally curious to know where/why TPG decides PDF over HTML. It may be that your decision is something for me to take on. However I’ll jump into the PDF now



  2. @Chris – This was produced as a PDF as it is a document handed out during training and workshops. It’s also emailed to clients. We’re looking at publishing it as HTML too.
