Looked at the developer's three Duo screenshots: a coloring page on the cover with a floating reference picture, and two open canvases with the reference beside the artwork. The cover image is 1398 by 2034 pixels.
Poses shown: Closed, Open. These are observations of the evidence, not a test of every interaction.
App version: Not recorded in this evidence.
Stills from the developer's page only: the app version, Xcode version and capture setup aren't given. No build was run, so folding between layouts and coloring aren't shown. Nothing shows the half-folded or standing pose.
