Accessibility Comments

The app works really well with VoiceOver. The interface takes just a little time to get used to, but once you explore it, including the settings, you’ll see it’s actually very easy to use.

VoiceOver Performance

VoiceOver reads all page elements.

Button Labeling

Most buttons are clearly labeled.

Usability

The app is fully accessible with VoiceOver, but the interface could be easier to navigate and use.

Other Comments

The app currently supports English (UK and US) and Italian, with plenty of high-quality voices to choose from. Some words may have pronunciation errors, but these can easily be fixed using the built-in pronunciation dictionary. It also lets you export generated speech as audio files. For just two euros, it offers incredible value. The developer is very responsive too—when I first purchased the app it wasn’t fully accessible, but after I reached out by email, accessibility was added very quickly.

Hello, as far as I know, Apple still doesn’t allow third-party TTS to be used as the system TTS for VoiceOver. When it comes to using the voices outside the app, the only option is to export the audio file generated within the app.
