iOS 27.3 beta brings three new iPhone features including a redesigned Health app

What is coming in iOS 27.3

Apple is preparing the iOS 27.3 software update for iPhones, and it is already available in beta testing. According to 9to5 Mac, the update carries three notable additions: a redesigned Apple Health app, a new karaoke video feature in Apple Music called Selfie Sing, and improvements to the StandBy lock screen mode. The site reports that the update should launch next month.

The Health app changes apply to iPhones that support Apple Intelligence, the company's suite of on-device and cloud AI features. The other two additions are not limited to those models.

A rebuilt Apple Health app with new tabs

The most substantial change is a new version of the Apple Health app. It introduces two extra tabs, called Insights and Longevity, which offer personalised and intelligent recommendations about a person's health.

Among the new capabilities are educational videos presented by clinical experts, movement evaluations recorded at home with the iPhone's camera, and the option to order and log laboratory tests. 9to5 Mac describes these as part of a much broader set of additions to the app.

The rollout has taken a detour. Apple first tried the new Health app in the iOS 27.2 beta, but pulled it before that version reached the public. The company said at the time that the app would come back and ship later in the year, and its arrival in the iOS 27.3 beta now confirms that plan.

Selfie Sing turns Apple Music into a karaoke camera

Apple Music gains a feature named Selfie Sing in iOS 27.3. It uses the iPhone's camera together with the service's built-in lyrics display to record karaoke videos of the person singing.

The lyrics appear on screen beneath the camera feed, so the singer can follow along and then share the finished video on social media. 9to5 Mac notes that the feature is clearly aimed at platforms such as TikTok, and calls it one of Apple's few offerings designed with social sharing in mind.

The site also observes that Selfie Sing will not appeal to everyone, describing it as a fun addition rather than an essential one.

StandBy upgrades that started on iPhone Duo

StandBy, the full-screen mode an iPhone shows while charging, receives several improvements in iOS 27.3. When the iPhone Duo launched, it came with a range of StandBy features that were exclusive to that model. This update extends them to other iPhones.

The Analog and Digital Clock faces have been redesigned, with more options for customising their colour and complications, the small pieces of extra information shown on a clock face. The Photos face has also been updated so that people can choose Shared Albums as its source.

In addition, iOS 27.3 allows several versions of each face to be created, making it easy to swipe between them. As 9to5 Mac points out, none of this will be new to iPhone Duo owners, but it brings the same options to a wider range of iPhone models.

What it means for iPhone owners

The Health app overhaul is likely to be the headline change for most people, since it applies to every iPhone that can run Apple Intelligence and adds tools that go beyond simple activity tracking. Ordering and logging lab results, and recording movement evaluations at home, point to Apple pushing further into personal health management.

Selfie Sing and the StandBy changes are smaller in scope, but they show Apple refining features across its software rather than reserving them for its newest hardware. Readers who want the new Health app should note that it depends on Apple Intelligence support, so older iPhones will not receive that part of the update.

As with any beta software, the exact timing of the public release and the final feature list could still change before Apple ships iOS 27.3.
