What's a good iOS app for accessing digital textbooks with VoiceOver support?

ReadAnywhere is a solid choice for accessing digital textbooks with VoiceOver on iOS. According to user reviews, the app is specifically designed for efficient VoiceOver users, with action items that move logically between sections and a chapter slider that's easy to locate by touch. A key benefit is the reduced verbosity, which is a welcome change from the experience on computers. The app also avoids initial focus issues that can occur when navigating between sections on the web. While some features like matching terms and definitions and writing in text boxes may have occasional unreliability, the overall experience is significantly more convenient than using a computer for screen reader users. The annotation feature allows text selection using the rotor, further enhancing accessibility.
