The iPhone Duo is not just a bigger iPhone that happens to fold. One of the biggest changes Apple has made with its first foldable is how iOS uses the extra screen real estate when the phone is opened. The 7.6-inch inner display can show two apps side by side, bringing a form of multitasking to the iPhone that has long been familiar on tablets and competing foldables.That changes what you can do with the Duo. And things get better if you are a professional who highly depends on your smartphone or a content creator. You can keep a webpage open while taking notes, compare responses from two AI assistants, follow directions while messaging someone or check your calendar while replying to an email. Apple also lets users save frequently used app combinations, turning some of these pairings into repeatable workflows rather than one-off tricks.About The AuthorAarohy Kapoor is a dynamic content producer and editor, known for creating high-impact, consumer-first content across diverse categories including technology, home decor, health & fitness, food, pet care, sports and everyday lifestyle essentials.
