Pass-and-play battleship for two: flip the folded Duo to hand over the turn
Does Fleet Duo work on iPhone Duo?
Yes, from launch day, says its developer: stood half-folded like a laptop, your fleet faces you above the targeting grid, and flipping the phone hands the turn over. It isn't on the App Store yet.
- Developer claimedTim Haerle, the developer, in a submission to FoldHunt on October 16, 2026, saying the game is made for every pose except Split View and is in App Store review for launch day, and on the game's site (playduo.games), which shows it on a rendered iPhone Duo half-folded like a laptop. A search of the App Store found no listing yet; the site says it is coming soon there.

A battleship table
Half-folded like a laptop on a table, your fleet stands on the upright half and the enemy's waters lie on the half below, where you lock a square and fire.

Flip it to pass the turn
After each shot both boards are sealed and the screen says to turn the phone. Lift the folded Duo and roll it over its hinge: the other half lands on the table as the next player's base, and only their fleet comes back when they tap Ready.
About Fleet Duo
Fleet Duo is a battleship game for two people sharing one phone, or for one against a hidden computer fleet. Each side places five ships on a 16-by-8 chart, then takes turns locking a square and firing; a hull stays hidden until the last shot sinks it. Three matches are free, and €2.99 unlocks it for good, with no ads and no subscription.
On the iPhone Duo it’s a private battleship table. Stand the phone half-folded like a laptop and your fleet faces you above the hinge while you aim at the enemy’s waters below. After each shot both boards are sealed; lift the folded phone and roll it over its hinge, and the other half lands as the next commander’s base, so each player’s fleet stays their own. Tim Haerle says it’s made for every pose except Split View, and on other iPhones it plays on one screen, the grid with the fire button below it. It’s in App Store review, aimed at launch day.

· Developer media reviewed
Developer claimed · iphone-duo
Read the developer's submission and looked at the game's site: its pictures and handover video show the fleet board above the targeting grid on a half-folded Duo, the sealed Pass the board screen, and the folded phone rolling over its hinge.
Poses shown: Book. These are observations of the evidence, not a test of every interaction.
App version: Not recorded in this evidence.
The site's Duo pictures and video are renders on a 3D model of the phone, not captures from the simulator. The developer says the game also adapts to the cover, the open display and the phone stood up, but doesn't describe those layouts. It isn't on the App Store yet, so no build was tested.
