Submit Your watchOS Apps to the App Store

With watchOS 6, customers around the world can use the App Store on Apple Watch to easily discover, browse, search, and install apps directly on their wrist.

Build with the watchOS 6 SDK.

Build your apps using Xcode 11, test them on devices running watchOS 6, and submit them for review. Starting April 2020, all new apps and app updates submitted to the App Store must be built with the watchOS 6 SDK and support Apple Watch Series 4 or later.

Optimizing Your App

Deliver even more valuable user experiences with SwiftUI, Streaming Audio, Extended Runtime, and more on watchOS 6. Integrate machine learning, Shortcuts and Siri experiences, complications, and notifications to bring users timely information and provide an easy way to complete quick actions no matter where they are.

App Name and Description

Your iPhone app and your watchOS app 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 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.


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.
