A naval duel for two, with a fleet hidden on each half of the Duo
Does Peekaboard: 2 Player Game work on iPhone Duo?
Yes, and seen in the simulator: the developer's screenshots show the two-player board, a half of the sea each, and the handover screen. Folding up to peek comes from the developer's description.

Adapted for the fold

One board, two players
Open flat between you, each player has a half of the sea, with their own fleet on their side and the other player's grid across the fold. A handover screen asks the next player to confirm before their fleet appears.
About Peekaboard: 2 Player Game
Peekaboard is Navid Gooranourimi’s naval battle for two people sharing a phone, or for one against Captain Rojo. Lay the Duo flat between you and each player gets half the table; on your turn, fold it up toward you to see your fleet. A handover screen keeps the board hidden until the next player confirms it’s their turn. On other iPhones, you hold a button to peek. Navid Gooranourimi also made ComicFlow.

Looked at the four screenshots the developer labels as the iPhone Duo simulator: the handover between players, both fleets shown, placing ships, and a battle against Captain Rojo. Each player's sea grid faces the other's, with their own fleet on their side.
Poses shown: Open. These are observations of the evidence, not a test of every interaction.
App version: Not recorded in this evidence.
Still screenshots of the open display, with no app or Xcode version; the developer set the hinge angle with debug arguments. They don't show the phone folding or a game being played, and nothing was tested on a Duo. The handover screen is an overlay, not the cover display.
