Does ComicFlow - CBR & CBZ to PDF work on iPhone Duo?
Yes, and seen in the simulator: the developer's screenshots show two-page spreads either side of the fold and the library beside its covers. The Duo layouts came in version 3.5.

About ComicFlow - CBR & CBZ to PDF
ComicFlow is Navid Gooranourimi’s reader and converter for comics in CBR, CBZ and PDF. On the open Duo it shows a two-page spread, a page on each side of the fold, and puts the library in a sidebar beside your covers. Folding, opening or turning the phone keeps your place, the developer says. Bring your own comics: the illustrated samples in the screenshots don’t come with the app. Navid Gooranourimi also made Peekaboard.

Simulator verified · iphone-duo
Looked at four screenshots the developer labels as the open display of the iPhone Duo simulator: a spread read left to right, a manga read right to left, the library's sidebar beside its grid of covers, and six finished conversions. Each page of a spread sits on its own side of the fold.
Poses shown: Open. These are observations of the evidence, not a test of every interaction.
App version: Not recorded in this evidence.
Still screenshots with no app or Xcode version. The sample comics are AI-made artwork for the demo. They don't show the cover, a half-fold or the phone folding, and no build was tested.
