   “The iPhone Duo has an all-new form factor with multiple folding and orientation options, and app developers are having some fun with it. You can find quite a few apps using the foldable display in unique ways, many with skeuomorphic designs. Tiny Computers turns the ‌iPhone Duo‌ into a miniature retro computer, with options inspired by the Macintosh, Commodore 64, Amiga 500, iMac G3, iBook G3, and more. It works best with the ‌iPhone Duo‌ in a seated orientation, giving you a display and a virtual keyboard. Tiny Computers - for the iPhone Duo. Second look.

Made by the same developer as Tiny Computers, Fold & Squish lets you make Rorschach art with the Duo. You paint a design on one half of the Duo's display, close it, rub a finger over the outer display to "squish" the virtual paint, then open it up to see your finished design. iPad & Duo"> Fold & Squish: Paint, Fold, Squish!

   These clever apps show off the iPhone Duo’s potential

   TechCrunchPublished Oct 24, 2026Checked Oct 24, 2026

   “It’s been a long time since I’ve been genuinely excited about a new iPhone. For years, a new iPhone meant a device that was thinner, faster, and had a camera that came with incredible upgrades. At some point (and Apple devotees can debate which year’s model this was!), a new iPhone became an incremental upgrade. Slightly better, slightly faster. Maybe there was a new button to learn, a new charging cable , or a new notch on the screen , but the iPhone itself remained the same rectangular glass and metal handheld it always was. The iPhone Duo changes this, allowing Apple to enter the market for foldable phones with a phone that, while imperfect , is whimsical, fun, and, yes, actually exciting. It’s hard to say when the urge to acquire the iPhone Duo first kicked in. I’ll admit that it wasn’t during the official announcement , which left me feeling puzzled about the device’s potential. Do I actually want a phone that folds, I wondered? Was propping up the phone as a little tent to watch Netflix worth all that extra money? (The Duo starts at $2,000). As it turned out, the desire for the Duo grew on me as I saw developers embracing the new foldable design to create Duo-optimized apps. Apple’s software development community, after all, is what keeps me locked into the iPhone. Apple developers are active, creative, engaged, and still often build for iOS first – a must if you like trying things early.”

   Foldable smartphone (Wikipedia)

   WikipediaChecked Oct 24, 2026

   “A foldable smartphone (also called a foldable phone or simply foldable) is a smartphone with a folding form factor. While folding designs have been used previously in clamshell or "flip phone" models, the term "foldable" now generally refers to a newer style featuring flexible displays in which the display itself folds. Some variants of the concept instead use multiple touchscreen panels connected by a hinge. Various structural layouts exist in this category. Devices may fold horizontally on a vertical hinge into a wider, tablet-like form, which typically use an inward-folding booklet-style design with a smaller screen on the outside cover allowing interaction without opening the device. Some early devices, such as the Huawei Mate X, used an outward-folding design in which a single display would wrap around to the back of the device when folded. A more recent category is the emergence of tri-folds, which contain two hinges rather than one and allowing for even greater display sizes on the interior. Foldable smartphones in a clamshell form factor (folding vertically on a horizontal hinge) have also been produced.”
