iOS 27 revamps app icons with sharper Liquid Glass layers

At a glance:

• Apple introduces multiple Liquid Glass layers in iOS 27 app icons to improve sharpness and reduce blur.
• The new rendering pipeline removes tilt‑based shimmer and repositions highlights, making icons clearer and more detailed.
• Icon Composer receives updates to build multi‑layer icons and add refraction effects.

Icon redesign details

Apple's iOS 27 update introduces a fundamental shift in how its first‑party app icons are rendered, moving from a single, thick glass overlay to multiple, distinct Liquid Glass layers that sit inside the icon artwork. This change aims to address user complaints about blurriness that emerged with iOS 26, where a heavy specular sheen obscured detail. By layering the glass, Apple can maintain a subtle sheen while keeping the underlying artwork crisp and high‑contrast.

The new approach adds several transparent glass layers, each with its own refraction and edge highlight, which together produce crisper edges and higher contrast while keeping the signature glassy sheen subtle. These layers are composited during rendering, allowing the system to apply different visual effects to each plane. Developers can also fine‑tune how each layer interacts with the underlying artwork.

By separating the layers, Apple eliminates the heavy specular sheen that previously washed out detail, and the motion‑based shimmer that created a tilting illusion is removed, resulting in icons that look consistent from any angle. The refraction effects between layers are now selectively applied, enhancing depth without overwhelming the icon's core design. Edge highlights are positioned at the top and bottom, providing a subtle sense of volume without the dynamic tilt that confused users.

Additional iOS 27 updates

Beyond icons, iOS 27 also brings a dedicated Siri app with auto‑deleting chats, expanded AI writing tools that can rewrite and generate text, and a wallpaper generator that creates custom images via the Image Playground app. These features aim to deepen Apple's privacy positioning by keeping conversations temporary and giving users AI‑driven creativity. The wallpaper generator leverages the same Image Playground engine used for emojis, allowing seamless integration across the OS.

Apple Intelligence features will also allow users to generate shortcuts automatically, and the updated Writing Tools can perform more extensive rewriting and text generation than previous versions. The shortcut automation can trigger actions based on context, reducing manual setup for power users. Together, these enhancements broaden the AI capabilities of iOS 27 while maintaining a focus on on‑device processing.

Developer tools and preview features

Icon Composer has been upgraded to support multi‑layer icon creation and includes new annotation tools for adding refraction effects. Developers can now preview how each layer will render on different device screens in real time. This reduces the iteration cycle and ensures icons retain clarity across the entire iPhone and iPad lineup.

These changes are part of a broader set of Liquid Glass refinements announced at WWDC 2026, which also introduce a system‑wide transparency slider and improved material diffusion for better readability across the OS. The transparency slider lets users adjust the overall glass effect, while material diffusion improves text legibility on translucent surfaces. Apple says the combined updates will make the interface feel more cohesive and visually refined.
