Submit your watchOS apps to the App Store.

The App Store on Apple Watch lets users around the world discover, browse, search, and install apps directly on their wrist. And now you can deliver even more powerful and personal apps for Apple Watch with the new capabilities of watchOS 8.

Build with Xcode 13

Build your apps using the Xcode 13 Release Candidate, which includes SDKs for iOS 15, iPadOS 15, macOS Big Sur, tvOS 15, and watchOS 8. Starting April, 2022, all watchOS apps submitted to the App Store must be built with Xcode 13 and the watchOS 8 SDK.

Optimize for watchOS 8

With the Always-On Retina Display, your apps are always available at a quick glance. Gather HealthKit data and connect to Bluetooth peripherals in the background, delivering up-to-date information to your complications. AssistiveTouch makes your apps more accessible than ever. And the powerful new SwiftUI Canvas API lets you take advantage of the GPU in Apple Watch for rich programmatic drawing.

Test on device

Before submitting your app for review in App Store Connect, make sure that it follows the review guidelines, functions properly, and is ready to be publicly released.

Beta testing with TestFlight

Get valuable feedback with beta testing to make sure your app is ready for release. Upload your apps to App Store Connect and use TestFlight to test them on Apple Watch. You can even invite external testers.

Version and build numbers

If your watchOS app has an iOS companion app, make sure the version and build numbers for both apps are the same in the binary you upload.

App name and description

Your app’s name plays a critical role in how users discover it on the App Store. Choose a simple, memorable name that is easy to spell and hints at what your app does. Be distinctive. Avoid names that use generic terms or are too similar to existing app names. An app name can be up to 30 characters long. If your watchOS app has an iOS companion app, they share one name and one description.

The phrase “Apple Watch” cannot be included in your app name, but can be included in the description. Apple Watch should always be written in English, even when it appears within text of another language. Always write Apple Watch as two words with an uppercase “A” and an uppercase “W.” For more information, see the Marketing Resources and Identity Guidelines.

Keywords

Keywords are limited to 100 characters, and are shared between your iPhone app and watchOS app. Maximize the number of words that fit in this character limit by avoiding terms such as watch and app. Do not use the phrase Apple Watch. For more information on writing effective keywords, read the App Store Product page.

App icon

Your watchOS app icon should be visually similar to your iOS app icon to show users that they are connected. The file you upload will be a square version of your icon at 1024 x 1024 pixels. While this image is large for scaling purposes, your icon is usually seen at small sizes. Make sure that this image gracefully scales down to smaller sizes.

The system will resize your icon for the App Store and apply a circular mask. Do not upload a circular icon. Keep the design simple and note that elements on the outer edges will be obscured by the circular mask. Avoid using black in the background of your icon to keep it from blending in to the black Apple Watch home screen.

Before uploading your icon in App Store Connect, get more details on designing icons for Apple Watch from the Human Interface Guidelines.

Screenshots

You can upload up to 10 screenshots of your watchOS app in addition to 10 iPhone app screenshots. watchOS app screenshots used on the App Store are 368 x 448 pixels (44 mm) or 312 x 390 pixels (42 mm). Use the full space for the screenshot — do not frame the screenshot in an Apple Watch. Also avoid placing your watchOS app within your iPhone app screenshots.

Two screenshots are initially visible in the screenshot carousel. We recommend using these to focus on the most important features of your app. You can also order your watchOS app screenshots to demonstrate a sequence of interaction.

App previews

Your app preview may only use footage of your iPhone app, and footage must stay within the app. Do not change your preview to show your watchOS app.
