Developers Build Playful Apps for iPhone Duo's Foldable Screen

Several apps are taking advantage of the iPhone Duo's folding design with retro-computer, art, relaxation, and coloring experiences. Tiny Computers recreates classic machines, while Fold & Squish lets users make mirrored paint designs by closing the handset. Other options include Portal's guided environments and Lake's coloring pages.
The apps exploit the iPhone Duo’s several folding positions and orientations, often with interfaces that mimic physical objects. Tiny Computers costs $3.99 and presents vintage computer models such as the Macintosh, Commodore 64, Amiga 500, iMac G3, and iBook G3; seated use provides a screen plus a virtual keyboard with games, drawing tools, and hidden extras.
Fold & Squish, from the same maker, is free and lets users paint half the screen, close the phone, rub the outside to blend the image, then reopen it. A paid Sparkle Pack adds glitter, rainbow colors, and butterfly guides. Portal offers nature scenes with sounds and breathing exercises, while Lake provides artist-made coloring pages.
These playful foldable-screen apps could make new hardware feel more approachable, especially for people curious about retro computing, art, or relaxation. Developers may benefit from early experimentation, while users could discover novel ways to use a phone as a notebook, game console, or calming space. The impact likely remains modest and entertainment-focused, but it may influence how future foldable apps are designed and how consumers judge whether unusual form factors are worth paying for.
