iOS 27.3 Beta Unveils Revamped Health App, Selfie Sing, and Expanded StandBy Features

Key points

• iOS 27.3 beta introduces a new Health app with 'Insights' and 'Longevity' tabs, featuring AI recommendations, clinical expert videos, and at-home movement evaluations using the iPhone camera.
• Apple Music adds 'Selfie Sing,' a feature allowing users to create karaoke videos with on-screen lyrics for sharing on social platforms like TikTok.
• StandBy mode receives significant upgrades, including new Weather and Calendar faces, redesigned clock options, and support for Shared Albums, features previously limited to the iPhone Duo.
• Safari gains a new Vertical Tabs layout and an Adaptive Dark Mode feature for websites lacking native dark mode support.
• Siri AI capabilities are expanding, with first-party app integration arriving in December and third-party support expected in spring 2027.

Background

iOS 27.3 follows iOS 27.2, which introduced Siri AI memory and SynthID watermarking in October 2026. The update also builds on the iPhone Duo launch in October, which faced supply issues and early hinge concerns. Apple previously tested the new Health app in iOS 27.2 but removed it before public release, confirming it would return later in the year.

How outlets are covering it

9to5Mac emphasizes the user-facing features of iOS 27.3, particularly the Health app and Selfie Sing, while MacRumors provides a broader context of Apple's product launches and software updates. AppleInsider focuses on the evolving capabilities of Siri AI, noting that while first-party app integration is imminent, third-party support and more agentic features are still in development. All sources agree on the December 2026 release timeline for the public version of iOS 27.3.

Why it matters

iOS 27.3 represents a significant step in Apple's integration of AI and health features, aiming to compete with rival AI apps and enhance user engagement through social-centric features like Selfie Sing. The expansion of StandBy features to all iPhones also indicates Apple's strategy to unify its product ecosystem.

What to watch

The public release of iOS 27.3 is expected in December 2026. Apple is also planning to launch its HomeView smart home hub and updated Apple TV 4K box on November 13, 2026. Further updates to the iPad lineup are anticipated in the first half of 2027.
