How to Change the Look of Your iPhone Apps and Icons With iOS 18 Customization

Apple significantly expanded Home Screen personalization with the release of iOS 18, allowing users to modify app appearances in ways that were previously impossible without complex workarounds. Whether the goal is to create a sleek monochrome aesthetic, match icons to a specific wallpaper, or simply make icons easier to see, several built-in methods now exist to transform the iPhone user interface.

Changing the look of apps on an iPhone primarily involves two distinct paths: using the native iOS customization menu for system-wide styling or utilizing the Shortcuts app for individual, custom-designed icons.

Quick Summary of Customization Methods

To quickly update the appearance of all apps simultaneously, long-press any empty space on the Home Screen, tap Edit in the top-left corner, and select Customize. This opens a menu where icons can be set to Dark, Light, or a specific Tint. To replace a specific app icon with a unique image from the Photos library, the Shortcuts app remains the standard tool for creating custom aliases.

Using Native iOS 18 System Customization

The introduction of the "Customize" panel in iOS 18 changed the fundamental way users interact with their Home Screen. This method is the most efficient because it applies changes dynamically to all supported apps, including third-party ones that have updated their assets for the new system.

How to Access the Customization Menu

The customization controls are hidden behind the Home Screen’s edit mode, commonly known as "jiggle mode."

Go to any Home Screen page on the iPhone.
Touch and hold the background (any empty area between apps) until the icons start to jiggle.
Tap the Edit button located in the upper-left corner of the screen.
From the dropdown menu, select Customize.

A toolbar will appear at the bottom of the screen, providing several options to alter the visual style of every icon and widget.

Switching Between Light and Dark Icons

Apple now provides specific dark-themed assets for its native apps, and many developers have followed suit.

Light: This is the traditional look with vibrant colors and white backgrounds for many icons.
Dark: Selecting this option applies a black or dark-grey aesthetic to app backgrounds. This is particularly effective for users who prefer the OLED-friendly "True Black" look or want to reduce eye strain at night.
Automatic: This setting syncs the icon appearance with the system-wide Light/Dark mode schedule.

Applying a Custom Color Tint

The "Tinted" feature is perhaps the most dramatic change in recent iOS history. It strips away the original colors of the icons and applies a monochromatic filter based on a user-selected hue.

When "Tinted" is selected, two sliders appear. The top slider adjusts the color (hue), and the bottom slider adjusts the intensity or saturation. A helpful feature within this menu is the Eyedropper tool, located in the top-right of the customization panel. By tapping this and dragging the loupe over the wallpaper, the system automatically matches the app icons to a specific color present in the background image, ensuring a perfectly coordinated aesthetic.

Increasing Icon Size and Removing Labels

For those who prefer a minimalist or "clean" look, iOS 18 allows for the enlargement of icons. When the Large icon setting is toggled (represented by the larger square icon in the customization menu), the apps grow significantly to fill more of the grid space.

A notable side effect—often seen as a benefit—is that the text labels (the names of the apps) disappear in this mode. This creates a purely visual grid that emphasizes the icon design rather than the text. It is an ideal setup for users who recognize their apps by sight and want to reduce visual clutter.

Changing Specific App Icons Using the Shortcuts App

While the native system settings change the style of existing icons, the Shortcuts app is required to change a specific app’s icon to a completely different image, such as a custom-designed icon pack or a personal photo. This method creates a "bookmark" that opens the app, allowing for total creative freedom.

Step-by-Step Custom Icon Creation

Launch the Shortcuts app on the iPhone.
Tap the + icon in the top-right corner to start a new shortcut.
Select Add Action.
In the search bar, type "Open App" and select the action labeled Open App.
Tap the word App (highlighted in blue) and choose the specific application to be customized.
Tap the Information (i) icon or the downward arrow at the top of the screen.
Select Add to Home Screen.
Under the "Home Screen Name and Icon" section, tap the smaller icon.
Choose Choose Photo, Choose File, or Take Photo to select the new image.
Rename the shortcut to the original app name (or leave it blank for a minimalist look) and tap Add.

The new icon will now appear on the Home Screen. To maintain a tidy look, the original app can be moved to the App Library so only the custom version is visible.

Performance and Functional Trade-offs

Using Shortcuts for icons involves a few nuances. When tapping a custom shortcut icon, the system may occasionally display a small banner notification at the top of the screen confirming the shortcut has run. Furthermore, custom icons created via Shortcuts do not display notification badges (the red numbers indicating unread messages or alerts). For communication apps like Mail or Messages, many users prefer the native tinting method to keep these functional indicators visible.

Organizing the Layout for Better Aesthetics

Changing the look of apps isn't just about colors; it's also about spatial arrangement. With recent updates, the iPhone Home Screen grid is no longer strictly top-down and left-to-right.

Flexible Icon Placement

Users can now place app icons and widgets anywhere on the grid, including the bottom or sides, leaving the center or top empty to showcase the wallpaper. This is particularly useful for wallpapers featuring people or scenery where icons previously blocked the focal point. By combining this flexible placement with "Large" icons and a specific "Tint," the iPhone UI can be transformed into a highly personalized dashboard.

Utilizing Widget Stacks

Widgets significantly impact the "look" of apps by breaking up the uniformity of the icon grid. Creating a "Smart Stack" allows multiple widgets to occupy the same space. To do this, drag one widget of the same size on top of another. This keeps the Home Screen looking organized while providing quick access to different types of information.

Best Practices for a Cohesive Home Screen Look

To achieve a professional-grade aesthetic, consider the following design principles when modifying app appearances:

Color Harmony: When using the Tinted feature, choose a color that complements the wallpaper. If the wallpaper is a sunset, a warm orange or deep purple tint often looks better than a clashing bright green.
Consistency: If using the Shortcuts method, try to use icons from the same "icon pack" to ensure that line weights, shadow styles, and illustration types match across the entire screen.
Balance: Mixing large widgets with enlarged icons can make the screen feel cramped. Use white space (empty grid areas) to give the eyes a place to rest.
Accessibility: While the "Clear" or "Translucent" styles introduced in some iterations of iOS provide a modern look, they can reduce legibility. Ensure there is enough contrast between the icon and the background to find apps quickly in a hurry.

Frequently Asked Questions

Why don't some of my apps change color when I use the Tinted feature?

Most apps will adopt the tint automatically by applying a filter over the existing icon. However, if an app has a very complex design or hasn't been updated for iOS 18, the tinting might look slightly distorted or less clean than native Apple icons.

Does changing app icons affect the app's performance?

Using the native "Customize" menu (Tinted, Dark, Large) has zero impact on performance. Using the Shortcuts method adds a very slight delay (milliseconds) because the system must trigger the Shortcut before launching the app, though this has been significantly optimized in recent iOS versions.

How do I revert my icons back to their original look?

To reset the icons, enter the Customize menu again (Long-press Home Screen > Edit > Customize) and select Default. This will immediately restore the original colors and sizes of all icons.

Can I hide app names without making the icons larger?

Currently, the native iOS way to remove app labels is to switch to the "Large" icon size. There is no official setting to keep icons small while removing the text.

Where can I find custom icon packs for the Shortcuts method?

Many designers offer icon packs on platforms like Gumroad, Etsy, or dedicated aesthetic websites. Look for files in PNG format for the best results when uploading via the Shortcuts app.

Summary of Icon Customization Options

The ability to change how apps look on an iPhone has evolved from a restrictive grid to a versatile design canvas. By leveraging the native iOS 18 customization toolbar, users can instantly apply Dark mode or Color Tints to their entire collection of apps, providing a unified and modern feel. For those seeking even deeper personalization, the Shortcuts app allows for the replacement of any icon with a custom image. Combining these tools with flexible grid placement and coordinated widgets ensures that every iPhone can truly reflect the personality and style of its owner.
