Apps turn the iPhone Duo into a mini computer, game console and more
Developers are building apps around the iPhone Duo’s folding screen, using its different positions to create unusual experiences.
The examples include Tiny Computers, which imitates retro computers, and TypeDraw, which makes the phone look and work like a notebook.
Fold & Squish uses the screen’s two halves to create mirrored paint designs, while Toastie turns closing the phone into a grilled-cheese-making game.
The Delta emulator uses the Duo like a Nintendo DS, with game controls on the screen and a sleep mode when the phone is closed.
Other apps use the larger display for coloring, meditation, focus timers and sleep timers.
These examples show how the foldable design can change how apps are used, beyond simply giving users a bigger screen.
The apps have different prices and features, and the examples described do not say what updates or new apps may come next.
