Developers who make apps for Apple’s platforms are used to opening App Store Connect in a browser to manage their apps in the App Store. This portal provides access to edit an app’s description, screenshots, keywords, and also follow sales reports, analytics, and customer reviews. There’s also an official iOS app from Apple available in the App Store that gives access to some limited functionality.

During this year’s WWDC, Apple announced the launch of an official API for App Store Connect, to let developers create their own tools using an officially supported API rather than the hacks that were previously required. Indie developer Vadim Shpakovski announced NativeConnect, a native Mac app to access the same features offered by the web version of the portal. Today, NativeConnect is available on its website.
