A new Ambient Music section in the Control Center now provides one-tap access to curated playlists, which are specifically designed to match your mood—be it Focus, Sleep, Chill, or Energy. Furthermore, these playlists blend seamlessly with the interface, and they can also be customized to align with your personal taste or daily routines.

Redesigned Control Center

iOS 18.4 introduces a revamped Control Center, featuring cleaner visuals, smoother transitions, and modular customization. As a result, you can now rearrange toggles, add third-party app controls, and prioritize your most-used features—similar to how widgets function on the Home Screen.

Photos and Album Enhancements Smarter Filters and Album Control

The Photos app now offers granular filtering. You can sort by “Not in Album” or “Shared With You,” making it far easier to manage large photo libraries. You can also now select a “Key Photo” for albums or even hide sensitive ones from your Recently Viewed list.

These quality-of-life improvements make organizing and reliving memories far more intuitive and private.

Upgraded App Store and Shortcuts

AI Review Summaries

Sick of reading through endless app reviews? Fortunately, iOS 18.4 introduces AI-powered summaries, which provide a quick snapshot of what people like—and dislike—about an app. As a result, this feature helps you make faster and smarter decisions.

New Shortcuts to Automate Everything

There are now even more Shortcuts Actions for apps like Safari, Maps, Calendar, Reminders, and Notes. Whether you want to automate your morning routine or create a workflow for content creation, it’s all possible—and easier—than ever before.

Driving and Navigation Made Better Enhanced CarPlay Interface

CarPlay users can now benefit from a third row of icons for larger displays, which means less swiping and more focus on driving. In addition, with Passenger Mode, someone riding with you is able to control music, navigation, and messaging directly from their own phone—all without interfering with your screen.

Set Your Default Navigation App

In response to user demand and EU regulations, iOS 18.4 lets users select Google Maps, Waze, or other apps as the default for navigation. This flexibility adds convenience, especially for users who prefer alternatives to Apple Maps. Accessibility for All.

Smarter Voice Control

Voice Control now supports contextual understanding. You can say things like “Scroll down,” or “Reply to the third message,” and your iPhone will execute them precisely—even across multiple apps. You can also set custom voice commands to automate sequences like launching apps or turning on Focus Mode.

Next-Level AssistiveTouch

AssistiveTouch has become more intuitive, supporting gesture layering, enhanced haptic feedback, and smarter edge detection. It’s more than just a tool—it’s now a fully integrated accessibility layer for users with limited mobility.

iCloud and Storage Improvements

Smarter Cleanup with Suggestions

Tired of running out of space? To address this, iOS 18.4’s Smart Storage Suggestions scan your device and provide quick recommendations—such as deleting duplicate photos, clearing caches, or archiving old messages. Moreover, you can even automate cleanup tasks on a schedule, making it easier to manage your storage efficiently.

iCloud+ Features Expanded

iCloud+ now includes Private Relay 2.0 for faster, more secure browsing. You also get better Hide My Email integration and can share your iCloud+ plan with up to 10 family members, making cloud storage more collaborative and cost-effective.

Your Health, Your Data New Metrics in the Health App

With the latest update, Apple adds hydration tracking, mood journaling, and walking steadiness monitoring. These metrics help you better understand your body and mind—and detect patterns early.
You’ll also find smarter trend analysis, where your iPhone alerts you if something is off—like declining sleep quality or irregular heart rate.

Mental Health & Sleep Support

The Health app now features guided meditations, mood check-ins, and personalized mental wellness summaries. Additionally, sleep tracking has been refined with more detailed visuals that display light, deep, and REM stages—along with smart bedtime suggestions based on your usage and lifestyle.
