iOS 27.3: Three new iPhone features coming soon

Apple placed iOS 27.3 into active beta testing ahead of a planned public release next month, introducing functional updates across system applications, as detailed in 9to5Mac's report. The release packages three primary feature additions: a rebuilt Apple Health application, a social karaoke recording tool inside Apple Music called Selfie Sing, and an expanded roster of StandBy display faces ported from the hardware launch of iPhone Duo.

This overview breaks down every functional change confirmed in the beta, covering system prerequisites, visual interface adjustments, and cross-device availability for daily iPhone users. It tracks how Apple is reintroducing health capabilities pulled during previous testing cycles, expanding music playback into user-generated video creation, and unlocking previously device-gated lock screen widgets across the broader iPhone hardware ecosystem.

01Health insights and longevity tracking tabs

The rebuilt Apple Health experience arrives specifically for Apple Intelligence-enabled iPhones, reorganizing wellness metrics around two dedicated surfaces labeled Insights and Longevity. These sections generate personalized recommendations grounded in algorithmic assessment, paired with instructional videos led by clinical experts. Users also gain access to camera-based movement assessments designed for guided physical evaluations directly from home without dedicated medical hardware.

Beyond internal motion analysis, the update integrates laboratory diagnostic tracking directly into the primary application interface. Users can order lab tests and record incoming panel results alongside standard biometric metrics. Apple initially tested this overhauled health layout during the iOS 27.2 beta cycle before removing it ahead of general availability, confirming at the time that the feature set would return later this year in the iOS 27.3 milestone.

02Social karaoke recording through Selfie Sing

Apple Music receives an interactive recording mode dubbed Selfie Sing, positioning the platform toward short-form social video sharing on networks such as TikTok. The tool pairs the front-facing iPhone camera sensor with Apple Music's existing synchronized lyrics engine. The interface positions real-time scrolling lyrics directly beneath the live video preview, allowing singers to track timing without looking away from the camera lens.

Captured sessions save as combined audiovisual files ready for export across external social services. The feature marks an explicit push into social-centric functionality for a streaming service that has historically prioritized passive playback and curated library management over direct user content creation.

03StandBy display faces from iPhone Duo

Apple is expanding StandBy mode by porting interface components that originally launched as exclusive software features on iPhone Duo. The incoming update brings all-new dedicated faces for Weather and Calendar, alongside refreshed layouts for both Analog and Digital clock views that expand user control over complications and accent palettes. The Photos face also receives a functional boost, adding support for selecting user-curated Shared Albums rather than relying solely on automated image selections.

04Face customization and version switching mechanics

Beyond the new aesthetic options, StandBy mode gains structural upgrades that allow users to configure and preserve multiple iterations of the same underlying face template. Owners can establish several distinct configurations of a single clock or widget face, adjusting complication loadouts or color treatments across individual presets. Navigating between these customized versions requires only horizontal swipes across the active StandBy screen while docked.

These options were previously limited to iPhone Duo owners following that model's debut. With iOS 27.3, Apple aligns the StandBy software capabilities across all compatible iPhones, ensuring multi-face customization and extended album displays operate consistently regardless of whether the user owns a standard handset or dual-screen hardware.

# Stage configuration profile across local test hardware
xcrun devicectl device install app --device <device-identifier> <profile-path>

Testing teams must account for hardware-level segmentation across incoming features, as the expanded Health application requires an Apple Intelligence-capable processor, while Selfie Sing and the expanded StandBy face library run broadly across standard compatible models.
