Does Lumen Darkroom work on iPhone Duo?
Yes, the developer says so: Lumen Darkroom 1.0.7D added half-folded Duo layouts for editing and comparing, and 1.0.7D2 brought them to its Atelier painting room.

Version 1.0.7D2 extends the layouts to the Atelier painting room. The developer's product page also names the iPhone Duo. The current version is 1.0.8.
