Jack makes iTunes Connect convenient.

• Compose and upload your iOS and/or OS X app’s descriptions for the app stores with a responsive, native app.
• Updating localizations without waiting for page loads. Add sale price intervals via a convenient date picker.
• Jack makes presenting your iOS and OS X apps a breeze. It is a convenient front-end to the iTunes Connect Transporter and a powerful editor for your apps metadata.
• Manage screenshots with drag-and-drop, easily add pricing intervals, manage and localize your in-app-purchases.
• In addition to loading and editing the app metadata, it also loads the existing screenshots from iTunes Connect. Something that the Transporter doesn’t do.
