Totally inaccessible. After asking whether you want to store files on iCloud or only on the device, you are taken to the main part of the app, which VoiceOver treats as a blank screen.

The app is totally inaccessible.

Other Comments

I contacted the developer about the lack of accessibility of this app. Here is part of their response.

“You are correct in your understanding that previous versions of Wotja (specifically Wotja A 2018) had VoiceOver support. The no-longer available "Wotja A” apps were built on a different underlying platform to the "Wotja X” apps. For Wotja V19 we had to move all development to the platform in Wotja X which unfortunately has (at present) no support for VoiceOver. We had to move to this platform because it was the only platform that give us the ability to deploy Wotja on iOS, macOS, Windows and Android and, having one code base to work with, meant we could move it forwards faster and at the time have a chance at keeping those versions in sync.

I appreciate that the above explanation does not help you at all, but at least you know more about why it is that things are as they are… I appreciate it means you may not be able to use Wotja V19 and I can but hope that future versions of the platform we use may add support for VoiceOver...”

Note, the developer has now made the old version available for VoiceOver users.

where can we download this accessible version?

I totally missed it. I read it as the older version was available on the appstore, which it isn't, i tried to find it yesterday.

It's better to try cSound.
You can generate any music.
And accessibility is wow!
In fact it is a command line utility.
And you need to have any text editor.
And ahead!

Hello. I recently stumbled onto this and am very interested in its applications to go with a lot of poetry and other word bits that I do. However, I can't figure out how/where to read text, and it looks like this should be possible. Can anyone give me any clues on adding my own words to the generator input?
Thank you in advance.

This is a bit more of an autocreation tool, something generative, meditative. I know nothing about composing but would love something like this to use for tracks to back occasional spoken word projects.
