Accessibility Comments

The developer spent an incredible amount of time to listen and to implement features which significantly improved accessibility for this version for VoiceOver users, including private/test versions to make sure everything works as expected.

There are specific controls for VoiceOver (i.e. a page control on the _now playing_ screen, as well as various hints, specific button and text labels to ease use and convey information.

VoiceOver Performance

VoiceOver reads all page elements.

Button Labeling

All buttons are clearly labeled.


The app is fully accessible with VoiceOver and is easy to navigate and use.

Other Comments

The application works with the official SubSonic server, as well as self-hosted implementations (Gonic, LMS, Koozic, etc).

Thanks to its speed control and bookmarks feature, it works equally well with audio books.

The available in-app purchase is a tip jar, in case you wish to donate.
