Reading Systems Accessibility Support Roundup

Note: this article was last updated in August 2020.


Digital books are usually accessed using a reading app to open, read and navigate the content. There are many different reading apps available, so how do you discover which offer the accessibility features you need? Maybe you need to use it with a screen reader, or require the ability to change the visual presentation of the contents. Perhaps you need a read aloud feature or the capability to enlarge images.
Here we present a roundup of popular reading apps that can be used with EPUB titles. The summary reviews are based on detailed accessibility evaluations conducted by and with people with print disabilities. More information on our structured evaluation protocol is given at the end of this article.
The results of the evaluations were accurate at the time of publication but may not reflect all personal experiences which can be affected by the version of the reading systems, assistive technologies or the publication being read. The apps change constantly, and developers improve the features based on the feedback from our tests. You can always read the latest detailed test results at

Reading Apps Roundup

Amazon Kindle icon

Amazon Kindle

Books from the world’s largest eBook store are read using the Kindle app. The app is available on most computer and smartphone platforms, including Amazon’s own Fire Tablets. The Kindle app has been evaluated by our testers on iOS, Android, Windows and Fire tablets.

Our evaluators liked: Support for visual adjustments is good on all platforms. There are useful features in the app such as “word wise” that explains the more challenging words in the book. The voices on the Fire tablets are especially high quality and natural sounding. On some books, it is possible to combine the eBook and Audible audiobook for a synchronized reading experience (purchases necessary). Titles in the Kindle eBook store indicate whether they are screen reader supported or not.

Be aware: Heading navigation using Voiceover (iOS) or Talkback (Android) is not supported. Table navigation is poor. Image descriptions are not announced on iOS or Android. Print page navigation is not supported. There is no built-in read-aloud feature in the app on Android, and the Speak Screen feature on iOS does not provide visual emphasis of the words being spoken. Your own EPUB titles cannot easily be loaded into the app. The Windows Kindle app supports more screen reader features than other platforms. The Kindle apps can provide a great way to read books such as novels. For more complex titles that include images, tables, figures and references you may be better off looking elsewhere.

Apple iBooks icon

Apple Books

Apple’s bookstore uses the Apple Books app (which used to be called iBooks). If you have an iPhone, iPad or Mac, the app will already be installed.

Our evaluators liked: the visual display of the title can be adjusted to suit the reader’s needs. Some images enlarge to full screen when selected, useful on a smaller screen and to people with low vision. The speak screen feature of iOS provides a read aloud feature with different options for visual emphasis.

Be aware: Apple Books is not available on Android or Windows.

Adobe Digital Editions icon

Digital Editions

Adobe’s reading software is widely used for reading PDF files, but it reads EPUB as well. The app is available on most phone and computer platforms. It is often recommended by public and academic libraries. Indeed, it is the only option for titles from some library systems because they use Adobe copy protection. Sadly, it is hard to recommend due to poor stability and lack of fundamental accessibility features.

Our evaluators liked: it is convenient to have PDF and EPUB reading in the same app.

Be aware: Our evaluators found Digital Editions on Windows to be unstable and it struggled with larger books. Reliability issues are also reported on iOS and Android. Navigating the table of contents with a screen reader was unsatisfactory. There is no function to change the screen colors or font, and no built-in read-aloud feature, limiting the appeal to people with learning differences such as dyslexia.

Dolphin EasyReader App icon

Dolphin EasyReader

This specialist reading app for Windows, Android and iOS is designed to provide many features required for people with reading disabilities. Several file formats in addition to EPUB are supported. A version for Amazon tablets (FireOS) is coming soon.

Our evaluators liked: Many useful features are provided for people with print disabilities, including screen reader support, several options for visual adjustments and read aloud. The app can be used to open titles on your device, and it also connects directly to the special library services in many countries (you need an account). The mispronunciation of words by the read-aloud feature can be corrected. An enhanced version of the app is built into the BrailleNote Touch device from Humanware.

Be aware: Continuously reading with a screen reader stops after a few pages due to the way the app displays the title. On Android and Windows hyperlinks are not followed when using a screen reader.

Kurzweil 3000 logo


Kurzweil 3000

The web license version of Kurzweil 3000 offers a powerful study aid for learners with reading differences such as dyslexia. Content, including EPUB 3 titles, can be uploaded to the ‘Universal Library’ from the local computer, Google Drive or Bookshare. A Chrome and Firefox extension can also be used to add read-aloud features to the browser, which can work with EPUBs read on some library platforms.

Our evaluators liked: The familiar features of Kurzweil are available in EPUB files, including flexible read aloud modes with high-quality voices, dictionary, picture dictionary, thesaurus, translations and study highlighters. Several different background colors are offered. The table of contents is available through the ‘bookmarks’ menu.

Google Play Books icon

Play Books

The eBooks obtained from Google’s book store app are read in their Play Books app. The app is usually already installed on Android phones and tablets and can be downloaded for iOS devices from the Apple app store. The books can also be read using Play Books via a web browser on Windows, Mac, and Chromebook computers. Your own EPUB titles can be uploaded to your library through the app or using the Play Books website.

Our evaluators liked: eBooks and audiobooks can be read in the same app. There are several ways to customize the visual presentation, including color themes, line length and spacing. The simple to use built-in dictionary (just highlight a word) may be especially useful for people with specific learning disabilities.

Be aware: Continuous reading with Talkback on Android is not supported, so reading is limited to screen by screen. There is no read-aloud feature on iOS. On Android, the read-aloud feature could do a better job of pausing between heading and paragraphs, and it is difficult to control where it starts from.

Our evaluators liked: No software installation is needed, just point your favorite web browser at the RedShelf site. Colors, font, spacing and margins can be personalized. Read aloud highlights the current paragraph and also underlines each word as it is spoken. Word definitions are one step away, and it is easy to add highlights and create flashcards which are instantly stored in the cloud.

There are plenty of options for adjusting fonts and spacing. Strong screen reader support and a neat Read aloud feature offers good control and a couple of different display modes.

How the accessibility features were evaluated

Apps are evaluated using the protocol published at This accessibility testing protocol has been developed in collaboration with people with reading disabilities, accessibility experts, and reading system developers. It is an open effort, with the test process described on the website, and more than 70 volunteer testers with different reading disabilities collaborate in the testing effort.

The basic assumption of the approach is that apps should support reading by eyes, ears or fingers. It should be possible for users to read the content by:

  • adjusting the display such as adjusting font size and color combination,
  • reading the text with a screen reader or integrated read-aloud feature, and
  • reading the text on a refreshable braille display.

The apps are evaluated using different combinations, with and without assistive technology. All reading apps are tested using the same standardized test titles, to ensure consistency. The test files are available from

The evaluation protocol is free to use, and anyone can evaluate a reading system. If you are an app developer you can ask us to look at your app, and we will report the results back to you.
