When iOS 27 first came out back in June, MacRumors started working on a series of in-depth feature guides and how-tos that go through all of the updates in Apple's new software. Our ultimate guide aggregates all of our iOS 27 coverage, and it is useful for iPhone and iPad users new to iOS 27 or those who might want a recap on what's included. We've organized it by feature to make it easy to find what you're looking for.

Liquid Glass remains a central focus of the iOS 27 redesign, with options to tone down transparency and achieve clear app icons on the Home Screen. The update also expands Apple Intelligence capabilities, introducing new Siri AI features and Visual Intelligence tools. Communication apps receive significant attention, with Messages gaining new drawing tools and the ability to hide the dictation button, while Phone and FaceTime receive a consolidated feature overview.

Additional sections cover AirPods customization, Safari enhancements, and Apple Maps updates. The guide comprehensively addresses Mail, Calendar, Reminders, and Notes, highlighting new Markdown support. Health and Weather apps receive redesigns, and the Wallet section details seven new features. Home and HomePod functionality expands, though certain Apple Intelligence features now require a 2TB iCloud+ plan. Finally, the Shortcuts app becomes less intimidating, and the Lock Screen receives five new customization options including a compact clock and volume slider.
