Top 10 New Features in Apple iOS 27.3

Here are some of the most interesting features and improvements discovered in the first iOS 27.3 beta.

1. Siri AI Gets More Powerful

One of the biggest highlights of iOS 27.3 is the expansion of Siri AI capabilities.

Apple is working to make Siri more intelligent and useful by allowing it to perform additional actions across supported applications.

With the latest beta, Siri AI can interact with different apps and help users complete everyday activities.

Some examples include:

  • Managing calendar activities.

  • Organizing files and documents.

  • Managing Safari tabs.

  • Searching and organizing information.

  • Managing reminders.

  • Performing supported actions in Messages.

  • Controlling selected app functions.

These improvements could make Siri a more useful personal assistant for iPhone users.

Apple has also announced a developer preview that allows third-party developers to integrate their apps with Siri AI through App Intents.

This could open new opportunities for developers to build more intelligent app experiences.

2. Redesigned Apple Health App Returns

Another important addition is the return of Apple's redesigned Health app.

The updated interface introduces new ways to explore health and fitness information, including new Insights and Longevity sections.

The redesigned experience aims to make health information easier to understand and organize.

Users can expect a more structured way to explore health metrics, wellness information and fitness-related data.

The redesigned Health experience is particularly interesting for users who regularly monitor their health through an iPhone and Apple Watch.

3. Safari Gets Vertical Tabs

Apple is introducing a new vertical tabs option in Safari.

This feature offers another way to organize open browser tabs.

Instead of displaying tabs only in a horizontal layout, vertical tabs allow users to browse and manage tabs in a side-oriented arrangement on supported interfaces.

This can be useful for people who frequently open multiple websites while researching, shopping or working online.

Safari is also receiving an Adaptive Dark Mode option.

This feature aims to improve the browsing experience on websites that do not offer their own dark theme.

For users who browse at night, these changes could make Safari more comfortable to use.

4. Apple Intelligence Expands Siri AI Language Support

Apple continues to expand its artificial intelligence capabilities across different languages.

The company has announced support expansion plans for Siri AI involving:

  • Traditional Chinese

  • Vietnamese

  • Turkish

  • Norwegian

Language availability and rollout timing may vary, so users should check Apple's official announcements for their region.

Expanding language support could make Apple's AI features accessible to more users around the world.

5. Apple Music Introduces Selfie Sing

Music lovers have another interesting feature to explore.

The Apple Music Sing experience is gaining a Selfie Sing option that allows users to record videos of themselves singing along to supported songs.

Users can explore video recording and voice modification options and share their karaoke experiences.

This addition could make Apple Music more interactive, especially for people who enjoy karaoke and sharing music videos with friends.

6. Apple Fitness+ Adds Gym Strength Workouts

Apple is also expanding its Fitness+ experience.

The new Gym Strength workout option introduces a four-week workout plan based on factors such as:

  • Fitness goals

  • Previous workout experience

  • Available equipment

  • Personal schedule

The goal is to help users follow a more structured strength-training routine.

This could be useful for people who prefer gym-based workouts rather than exercising exclusively at home.

7. StandBy Mode Gets More Customization

Apple continues to improve the iPhone StandBy experience.

The latest beta includes additional customization options for supported clock displays.

Users can explore different clock configurations, colors and information displays.

These improvements could make StandBy more useful when an iPhone is placed on a charging stand.

8. Freeform Gets New Creative Tools

Apple's Freeform app is receiving additional creative features.

The new tools allow users to create custom editable shapes using text descriptions and work with additional image and formatting options.

There are also new text styles and background customization choices.

Some advanced creative capabilities are limited to Apple Creator Studio subscribers.

These changes could make Freeform more useful for brainstorming, planning and collaborative creative projects.

9. VPN Controls Get an Improvement

Apple is making changes to VPN controls in Control Center.

The updated VPN toggle allows users to switch between VPN connections more conveniently.

Previously, the control mainly enabled or disabled the last-used VPN connection.

This improvement could make managing multiple VPN connections easier for users who regularly switch between networks.

10. Additional Privacy and Accessibility Improvements

Apple continues to introduce smaller changes across the iOS experience.

The iOS 27.3 beta includes a Global Privacy Control option in Safari's advanced settings.

The update also introduces accessibility-related changes for supported devices.

As beta testing continues, additional improvements and bug fixes may appear in future versions.

How to Download and Install iOS 27.3 Developer Beta

If you are an eligible registered Apple developer, you can follow these steps to install the latest developer beta.

Step 1: Open the Settings app on your iPhone.

Step 2: Select General.

Step 3: Tap Software Update.

Which iPhones Support iOS 27.3?

iOS 27.3 is a version of Apple's iOS 27 software generation.

Compatibility depends on whether your iPhone supports the underlying iOS 27 release and whether the particular feature requires additional hardware or software capabilities.

Some Apple Intelligence features require compatible devices, supported languages and regional availability.

Not every iPhone will necessarily receive every new AI feature.

For the most accurate compatibility information, check Apple's official iPhone software support documentation.

iOS 27.3 vs iOS 27.2: What's New?

The new beta builds on the previous iOS 27 software generation with additional features and improvements.

Here is a quick comparison of the main changes highlighted in beta reporting.

Feature iOS 27.2 iOS 27.3 Beta

Health app Previous interface Redesigned experience returns
Safari Existing tab experience Vertical tabs and Adaptive Dark Mode
Apple Music Existing Sing experience Selfie Sing
Fitness+ Existing workouts Gym Strength plan

The table highlights reported changes rather than claiming that every feature is entirely new or available on every iPhone.

When Will Apple Release iOS 27.3 to the Public?

Apple has not confirmed an exact public release date for the final iOS 27.3 version.

The November 3 release is the first developer beta, meaning the software is still being tested.

Apple may introduce additional beta versions before releasing the stable update to eligible iPhone users.

The final release timing and feature availability will depend on Apple's testing process and official announcements.

Users who prefer stability should wait for the final public version instead of installing early developer software.

Is iOS 27.3 Worth Installing?

For developers and technology enthusiasts, iOS 27.3 beta offers an opportunity to explore Apple's latest software changes.

The expanded Siri AI capabilities, redesigned Health app, Safari improvements and new entertainment features make this an interesting beta release.

However, beta software is not always suitable for everyday use.

If you rely on your iPhone for work, banking, communication or other important activities, waiting for the stable release is generally the safer choice.
