From the Daisy Consortium:
Following feedback from our users who found the Ace by DAISY command line tool useful but in some instances challenging to use, we are delighted to bring you the new Ace by DAISY App.
The Ace by DAISY App is a desktop application available for Windows, MacOS and Linux, allowing EPUB accessibility testing directly from your desktop, helping to ensure your EPUB content conforms with the EPUB Accessibility 1.0 specification, and allowing all readers to access and enjoy your content.
Note this is a release candidate and you may encounter minor bugs which we will work to address in the coming months. For more information on this release visit the Ace by DAISY App page on Inclusive Publishing.
