Liquid Glass is Apple’s translucent, animated interface material and design language in iOS 26. It appears mainly on controls and navigation—such as buttons, toolbars, and tab bars—where it lets app content remain visible beneath a responsive, glass-like surface. It is a software design effect, not a screen coating, app, or product to buy.

What Liquid Glass looks like

Apple describes Liquid Glass as combining glass’s optical qualities with fluidity. In practice, interface surfaces can reflect and refract what is beneath them, respond to interaction, and shift as you scroll. The effect is intended to distinguish controls from the content they sit above without completely obscuring that content. Apple’s iOS 26 feature document describes the material as responding to underlying content in real time.

The name does not mean the iPhone display is made of liquid or glass. It refers to software-rendered appearance, movement, and transitions. Apple presents the design language across iPhone, iPad, Mac, and Apple Watch, though the details vary by platform and interface.

Where you may see it on iPhone

Liquid Glass is primarily for the functional layer of an interface: controls and navigation that sit above app content. Familiar examples include buttons, switches, sliders, tab bars, toolbars, navigation bars, and sidebars. Their appearance can change with interaction or scrolling.

In Apple’s WWDC25 UIKit session, tab bars are shown floating over content and minimizing during scroll, alongside updated navigation and toolbar appearances. These are examples of platform behavior, not a guarantee that every third-party app will look or behave identically. An app’s appearance depends in part on how it is built.

Does Liquid Glass change how apps work?

Liquid Glass is principally a visual and interaction-design change; it does not, by itself, mean an app’s purpose or features have changed. Standard controls can adopt the new appearance while continuing to perform their familiar roles.

Apple says standard SwiftUI, UIKit, and AppKit components use the latest appearance when apps are built with the latest SDK for current platform releases. Developers can also apply the effect to custom interface elements, but are advised to do so selectively. Apple’s Liquid Glass overview explains the material and framework support.

At launch, Apple said apps built with Xcode 16 kept their prior interface on iOS 26, while rebuilding with Xcode 26 brought the new design to standard controls. That was launch-era guidance, including a temporary compatibility option; it should not be treated as a statement of the current option’s availability. Consult Apple’s current release documentation for present-day Xcode and iOS behavior. The original discussion is in Apple’s WWDC25 Platforms State of the Union.

Can you make Liquid Glass less transparent?

There is no need to assume every interface will look equally transparent. Apple says the material can adapt to appearance preferences and accessibility settings, including Reduce Transparency, Increase Contrast, and settings that reduce motion. System controls handle relevant adaptations; custom app interfaces may vary. If the effect is difficult to read, check the display and accessibility options available on your iPhone under Settings, then Accessibility, and review the relevant Display & Text Size and Motion controls. Exact labels or availability can vary by iOS version.

Apple’s adoption guidance advises developers to test custom colors, views, and animations under different settings, and to provide accessibility labels for toolbar icons.

Why Apple recommends using it selectively

Apple’s Human Interface Guidelines separate the functional interface layer from the content layer. Liquid Glass is meant for controls and navigation; standard materials are generally more appropriate for app backgrounds and content surfaces. Applying the glass effect everywhere can compete with the content and make the interface hierarchy harder to understand.

The clear variant is intended for components placed over visually rich backgrounds, rather than as a default treatment for every surface. Apple’s Materials guidance explains the distinction and cautions against overuse. Developers can find platform examples in Apple’s WWDC25 UIKit design session and its WWDC25 design-system session.
