Apple Presentation Background Screen Setup Hardware

App Icon

Every app needs a beautiful and memorable icon that attracts attention in the App Store and stands out on the Habitation screen. Your icon is the first opportunity to communicate, at a glance, your app's purpose. Information technology also appears throughout the system, such equally in Settings and search results.

Cover simplicity. Notice a single element that captures the essence of your app and express that element in a simple, unique shape. Add details charily. If an icon's content or shape is overly complex, the details tin be hard to discern, especially at smaller sizes.

Provide a single focus point. Blueprint an icon with a single, centered point that immediately captures attending and conspicuously identifies your app.

Design a recognizable icon. People shouldn't take to analyze the icon to figure out what it represents. For example, the Mail app icon uses an envelope, which is universally associated with mail. Take time to design a cute and engaging abstract icon that artistically represents your app's purpose.

Keep the groundwork simple and avoid transparency. Brand sure your icon is opaque, and don't ataxia the background. Give it a uncomplicated background so it doesn't overpower other app icons nearby. You don't need to fill the entire icon with content.

Use words only when they're essential or part of a logo. An app's name appears below its icon on the Home screen. Don't include nonessential words that repeat the name or tell people what to exercise with your app, like "Lookout" or "Play." If your pattern includes whatsoever text, emphasize words that chronicle to the actual content your app offers.

Don't include photos, screenshots, or interface elements. Photographic details can be very hard to see at small sizes. Screenshots are likewise complex for an app icon and don't mostly help communicate your app's purpose. Interface elements in an icon are misleading and confusing.

Don't use replicas of Apple hardware products. Apple products are copyrighted and tin can't exist reproduced in your icons or images. In full general, avoid displaying replicas of devices, because hardware designs tend to change oft and can make your icon wait dated.

Don't place your app icon throughout the interface. It can be confusing to run across an icon used for unlike purposes throughout an app. Instead, consider incorporating your icon's colour scheme. See Color.

Test your icon against dissimilar wallpapers. Yous tin can't predict which wallpaper people will choose for their Home screen, so don't just test your app against a light or dark color. Run across how it looks over different photos. Try information technology on an actual device with a dynamic background that changes perspective as the device moves.

Go along icon corners square. The system applies a mask that rounds icon corners automatically.

App Icon Sizes

Every app must supply small icons for display on the Habitation screen and throughout the organisation when your app is installed, every bit well every bit a larger icon for brandish in the App Shop.

Device or context	Icon size
iPhone	60x60 pt (180x180 px @3x)
	60x60 pt (120x120 px @2x)

iPad, iPad mini	76x76 pt (152x152 px @2x)
App Shop	1024x1024 pt (1024x1024 px @1x)

Provide different sized icons for different devices. Make sure that your app icon looks great on all the devices you support.

Mimic your small icon with your App Store icon. Although the App Store icon is used differently than the small one, it's even so your app icon. It should generally lucifer the smaller version in appearance, although it can be subtly richer and more detailed because there are no visual effects applied to it.

Spotlight, Settings, and Notification Icons

Every app should also provide a minor icon that iOS tin display when the app proper noun matches a term in a Spotlight search. Additionally, apps with settings should provide a small icon to display in the built-in Settings app, and apps that support notifications should provide a pocket-size icon to display in notifications. All icons should clearly identify your app — ideally, they should match your app icon. If you don't provide these icons, iOS might shrink your primary app icon for display in these locations.

Device	Spotlight icon size
iPhone	40x40 pt (120x120 px @3x)
	40x40 pt (80x80 px @2x)
iPad Pro, iPad, iPad mini	40x40 pt (80x80 px @2x)

Device	Settings icon size
iPhone	29x29 pt (87x87 px @3x)
	29x29 pt (58x58 px @2x)
iPad Pro, iPad, iPad mini	29x29 pt (58x58 px @2x)

Device	Notification icon size

	38x38 pt (76x76 px @2x)
iPad Pro, iPad, iPad mini	38x38 pt (76x76 px @2x)

Don't add an overlay or edge to your Settings icon. iOS automatically adds a 1-pixel stroke to all icons so that they await good on the white groundwork of Settings.

TIP If your app creates custom documents, you don't need to design document icons considering iOS uses your app icon to create document icons automatically.

User-Selectable App Icons

For some apps, customization is a feature that evokes a personal connectedness and enhances the user experience. If it provides value in your app, you lot can let people select an alternate app icon from a set of predefined icons that are embedded inside your app. For instance, a sports app might offer icons for different teams or an app with light and night modes might offering respective light and night icons. Only users can choose one of the alternating app icons y'all supply, and the system always provides confirmation when people brand this change.

Provide visually consequent alternate icons in all necessary sizes. Similar your master app icon, you deliver each alternate app icon as a collection of related images that vary in size. When people choose an alternate icon, the organisation replaces your chief app icon with the accordingly sized alternating icon on the Habitation screen, in Spotlight, and elsewhere in the organisation. To ensure that alternating icons appear consistently throughout the system, provide them in the same sizes you apply for your primary app icon.

For programmer guidance, encounter the setAlternateIconName method of UIApplication.
