What's New in Unison Reader

1.0.7

October 23, 2026

• Made for iPhone Duo. Open it and your book lies open in two pages, one either side of the fold, turning a spread at a time like a printed book. • On iPhone Duo, the controls sit in one slim bar at the bottom, so more of the screen is the page. • Stand iPhone Duo half folded and the page sits on top, with large Back and Next buttons below the fold, for when your hands are busy. • On iPhone Duo, your library opens the same way: the book you're reading on the left, the rest on the right. • Audiobooks now start Chapter 1 from its first line, even when the book opens with pages the narrator doesn't read. • A download from your library server no longer gets stuck if you leave the app while it finishes.

Where has this been all my life

I love being able to listen on the go and read when I’m home. I’m a one-book-at-a-time kind of reader. It’s always annoying to have to re-find my place in book when switching between mediums.

Unison reader solves that!! And the plex-like functionality for hooking up your own server for hosting is amazing. Keep the updates coming. I love this app.
