Preparing Your
watchOS App
for Submission

watchOS 3 is in the hands of customers around the world. Prepare and submit your watchOS app, icon, screenshots, and description for review now.

Building Your watchOS App

Use the latest release of Xcode 8, which includes watchOS 3 SDK to build your watchOS 3 apps. As of June 1, 2016, all new watchOS apps submitted to the App Store must be native apps built with the watchOS 2 SDK or later. iPhone apps that introduce a new WatchKit extension for watchOS 1.0 are no longer accepted.

App Store Metadata

Make sure the metadata for your App Store product page includes your app’s functionality on Apple Watch.

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.

Do not upload a circular icon.
If your icon is designed with a white or light background, a hairline stroke will be added for display on the App Store.

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

Screenshots

You can upload up to five screenshots of your watchOS app in addition to five iPhone app screenshots. watchOS app screenshots used on the App Store are 312 x 390 pixels. 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.

Provide edge to edge screenshots that are 312 x 390 pixels (42 mm).
Don’t include Apple Watch in your 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 Name and Description

Your iPhone app and your watchOS app share one name and one description. If your iPhone app contains a watchOS app, Glance, or notification, mention this functionality early in your description and include it in the What’s New section. Do not include the phrase Apple Watch in your app name.

Using the name Apple Watch

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 details on using the name Apple Watch, read the App Store Marketing Guidelines.

App Preview

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. Learn more about app previews.

Uploading Your App

Before you submit your app, make sure that it adheres to the app review guidelines, the version and build number are consistent, and it is ready to be released.

App Review

All watchOS apps submitted to the App Store are reviewed based on a set of technical, content, and design criteria. Make sure to use our guidelines and resources before submitting your app for review.

Version and Build Number

Make sure the version and build numbers for your iPhone app and watchOS app are the same in the binary you upload.

Release Date

Once your watchOS app is approved and released by Apple, your existing iPhone users will receive the app update and customers will see your watchOS app icon and description on the App Store. For more information on submitting apps to iTunes Connect, read the iTunes Connect Developer Guide.
