The lock screen
The lock screen shows the iOS system player: the cover, the title, the chapter and a scale for the whole book rather than the current file.
- Start a book and lock the phone: the screen shows the cover, the title, the author and the current chapter.
- The scale covers the whole book: drag it and the book moves to that spot, even if it is in another file.
- The skip buttons use your intervals from Settings, not the system’s 15 seconds.
- The same goes for Control Center and the Dynamic Island.
Do not want people nearby to see the title? Settings → “Privacy” → “Hide the title on the lock screen”: it shows “Audiobook” instead, with no author and no cover.
