In the past few months, Apple has introduced several new features on iOS, iPadOS, and watchOS and tools on the App Store for developers to reimage their apps.
In late 2021, Apple allowed developers of reader apps to include “an in-app link to their websites for users to set up or manage an account” instead of only using the App Store sign-up system, new App Analytics metrics to get a better understanding of apps’ performance, the ‘account deletion within apps’ feature, updated the App Store Connect API with new customization and automated tools, and more.
iPhone and iPad apps. iOS 15 and iPadOS 15 let you take advantage of Safari web extensions, SharePlay and the Group Activities API, Focus, ShazamKit, Create ML, and more. You can also publish custom product pages and in-app events, and run product page optimization tests on the App Store on these platforms.
