iPhone Duo
Reading and listening on iPhone Duo
PageEcho is a reader app that becomes a two-page book when you unfold iPhone Duo and reads aloud on the outer display when it is closed. It is free to download, and the voices, translation and AI all run on the device.
Closed and unfolded
| iPhone Duo | What PageEcho does |
|---|---|
| Closed (outer display) | Shows one page on the outer display and reads it aloud in the voice you chose. |
| Unfolded | Becomes a two-page spread with the binding on the fold. Drag a page corner and it turns with your finger; playback controls sit on a rail at the edge, so they never cover the text. |
| Folding and unfolding | You stay on the same page and the same sentence. |
Beyond the reader
- Library, settings and AI chat Unfolded, the list and its content split across the two sides of the fold.
- Notices Messages such as a bookmark notice appear inside one half instead of across the fold.
- First launch The welcome pages turn like a book opened across both halves.
What opens as a two-page spread
Flowing text opens as a two-page spread: EPUB, TXT, Markdown, RTF, MOBI, AZW3, FB2 and web articles.
PDFs keep their own page layout and scroll one page at a time; unfolded, PDF search docks as a panel beside the fold.
