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 ($3. 99)
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. The mini computers have clickable keyboards, desktop games, and paint programs, along with hidden files and easter eggs. Fold & Squish (Free)
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. An add-on "Sparkle Pack" includes glitter paints, rainbow paint, and pencil guides for helping you paint designs like butterflies, but the base feature set is available for free. Portal ($2. 99/month)
Portal is a relaxation app that offers "portals" to different natural environments, from a lava river in Iceland to the cloud forest in Costa Rica. There are over 100 locations, each with calming sounds and breathing exercises. The app can be used for meditation, but it also has focus timers and sleep timers. When the ‌iPhone Duo‌ is unfolded, scenes take up the entire display, but it also works especially well when the ‌iPhone Duo‌ is in tent mode. There are three free portals to use that are refreshed each month, and a Premium subscription is priced at $2. 99 per month or $29. 99 per year. Lake (Free)
Lake is an adult coloring book that’s been updated for the ‌iPhone Duo‌. Holding the Duo in portrait mode gives you a full-page coloring surface, and the developer tells us it’s being updated for Apple Pencil . Lake has coloring pages from a long list of artists. It’s free to download and comes with basic coloring pages and tools, but unlocking the full app requires a premium subscription that’s $9. 99 per month. Toastie ($2. 99)
Toastie turns the ‌iPhone Duo‌ into a toaster for making grilled cheese sandwiches. It’s a game where you prepare the sandwich ingredients, then close the ‌iPhone Duo‌ to toast the sandwich. Timing is important, and the goal is to make a perfect grilled cheese. We turned the iPhone Duo into the world’s most expensive toaster 索
Build the sandwich quickly, then close your Duo to toast it. Don’t burn it though! Check it out: https://t. co/riRVUFLlm1 https://t. co/0llh2lv9R1

The app has Nintendo DS controls, and when you close it, it looks like the shell of the gaming system and puts the game you’re playing into sleep mode…
