I am the original author Pastime Audiobook Player, listed on AppleVis here:
Recently, my team and I have revamped Pastime in an attempt to strip away any unnecessary capabilities, so that it can be a truly simple and intuitive audiobook player for the visually impaired. It also works with VoiceOver enabled, though it is not optimal for VO users, though perhaps we can address VO users in a future release (or even a separate app).
We've just released the new version in the app store (it works on iphone and ipad) here:
We would love to hear any and all candid feedback and recommendations you have for us.
Thanks so much,
Andrew and the team at Proto
