Where Categories Are Displayed
You can assign two categories to your app — a primary and a secondary category. The primary category is particularly important for your app’s discoverability on the App Store, as this is where your app is displayed in search results and top charts.
Choosing a Primary Category
Let’s say you have a photo-sharing social networking app. You could choose either Photo & Video or Social Networking as your primary category. To decide which category will best serve your app, consider the following:
Make sure that the category you choose accurately reflects your app’s core experience. Choosing categories that are not appropriate for your app is against the App Store Review Guidelines.
Apps for kids. If you have an app designed for kids ages 11 and under, select the Made for Kids checkbox in iTunes Connect and choose an appropriate age band (5 and under, 6–8, or 9–11). Your app must comply with the App Review Guidelines for Kids apps and will go through review to be approved for the Kids category. In addition to the Kids category, your app can be discovered in another primary and secondary category (for example: Games, Entertainment, or Education).
Games. If your app is a game, you can choose up to two Games subcategories. Users can find your app by browsing the subcategories on the App Store and in the Games subcategory charts. If you don’t know which subcategory best suits your game, research the types of games in each before making your selection.
Stickers. In the App Store for iMessage, you can assign your sticker pack app to a category called Stickers, or to another primary category that best describes your app. If you use the Stickers category, you can also select a Stickers subcategory. Standalone sticker pack apps are not displayed in categories on the App Store for iPhone and iPad — they are discoverable only in search results. Categories for iOS app with iMessage extensions are taken from the iOS app and are used on the App Store for iPhone, iPad, and iMessage. For more details on the different types of iMessage apps and extensions, read iMessages + Apps.
Explore and compare categories to see which best describes your app.
