Getting Ready to Submit

Once you’re ready, use App Store Connect to test your app, prepare your product page, and submit. TestFlight in App Store Connect lets you distribute beta versions of your apps for valuable feedback. You can invite up to 10,000 testers using just their email address or a public link.

App Icon. Create and upload two sizes of your icon: one for the App Store for iMessage, and one for the App Store for iPhone and iPad. Download design templates to help create your icon in the required sizes from Human Interface Guidelines: Resources.

App Name, Subtitle, and Description. You can use the terms iMessage and Stickers in your app name, subtitle, or description. If you use these terms, don’t repeat them in your keywords, and vice versa.

Keywords. Carefully choose your keywords to ensure your app is easily discoverable in App Store search. Keywords are limited to 100 characters total, with words separated by commas and no spaces.

Screenshots. Showcase the iMessage experience by uploading up to five screenshots per localization on your app’s version page in My Apps. When showing conversations in Messages, make sure the information and accounts you display are not real. Do not display phone numbers.

App Preview. Your app preview footage demonstrates the features, functionality, and UI of your app. For iOS apps with iMessage or sticker extensions, you can show both the iOS app experience and the iMessage app experience. Do not show the Home screen or the transition from the app to the extension. App previews are displayed on the App Store for iPhone and iPad and are not displayed on the App Store for iMessage.

Category. The App Store for iMessage shows apps browsable by primary categories. The Stickers category appears at the top of the category list and also contains subcategories. This category is only available to standalone sticker pack apps and iMessage apps. You can choose Stickers as the primary category and one Stickers subcategory.

Categories for iMessage or sticker pack extensions are taken from the corresponding iOS app and used on the App Store for iPhone, iPad, and iMessage. iOS apps with iMessage or sticker pack extensions can’t choose the Stickers category.
