The current US App Store title is purrpage. Double-Page Reader, while its feature description still refers to Duo Reader. It brings books, PDFs, and RSS articles into one reading library with adjustable type, spacing, folders, search, and saved reading position. Readers can select passages to define, translate, highlight, or annotate, and ask Mochi to summarize a chapter. Natural-voice playback highlights sentences, while iPhone Duo can show a two-page spread with notes and translation beside the text. The developer says quick Mochi questions run on-device and require a device that supports Apple Intelligence. The listing does not specify pricing or the full range of supported ebook formats. Confirm device compatibility before relying on AI features.
