The iOS 27.3 beta has been released by Apple, introducing multiple new features and design changes. The Health app receives a redesigned interface that integrates Apple Intelligence, offering more intuitive navigation and predictive insights into long-term health trends, including Health Age and movement assessments. Safari gains Vertical Tabs, a left-hand tab list option that can display icons or full page titles, accessible via Settings. Adaptive Dark Mode in Safari allows pages without native dark themes to adopt a dark appearance. Siri AI app actions are expanded, enabling more complex tasks across Calendar, Files, Finder, Journal, Mail, Maps, Messages, Music, Notes, Photos, Preview, Reminders, Safari, Shortcuts, and Weather. StandBy mode is reimagined, with updated Analog and Digital Clock faces and new StandBy faces for Calendar and Weather, plus the ability to choose Shared Albums in Photos faces and to swipe between multiple face versions. Additional updates include new Gym Strength workouts in Apple Fitness+ and a Reachability option for iPhone Duo users to swap screen sides for easier one-handed use. Apple also adds new languages to Siri AI, such as Traditional Chinese, Vietnamese, Turkish, and Norwegian.
