I am the developer of Larkwire, an app that birders use to learn to identify bird sounds. I have just added VoiceOver accessibility support to the app and need beta testers.
The app uses a sequence of games to gradually teach you which sounds go with which species. If you have an interest in learning to identify which birds you're hearing, you'll love Larkwire. I know the accessibility support in this beta release isn't perfect, but with your help, I'll make it better!
You can install the beta version with this link: https://testflight.apple.com/join/4eUJPNNU
I suggest you install Apple's TestFlight app, first, as it will make the Larkwire installation go smoother.
Also, during the beta test you can purchase any of the content within the app and you will not be charged.
