iPhone Duo apps showcase foldable screen creativity

Apple's first foldable iPhone, the Duo, has sparked developer creativity with apps designed to use its dual screens, showcasing the device's unique potential beyond standard upgrades. These apps range from retro music players to flight trackers, making the $2,000 phone more appealing. Netflix, a launch partner, lets users scroll short-form clips on the outer screen and continue on the larger inner display. Other notable apps include Deck-Man, a cassette player simulator, and TypeDraw, a virtual notebook, all built to exploit the foldable form factor. The Duo's app ecosystem is still developing, with many mainstream apps not yet optimized. However, early favorites like Wakeout, Flighty, and Tiny Computers demonstrate the device's versatility, offering features like tent-mode flight tracking and retro computer simulations, with more apps expected soon.
