Apple App Store

Apple’s online store for browsing, purchasing, and downloading apps for its iOS devices (iPad, iPhone, iPod Touch, iPad mini). Also known as the iTunes Store.

App Studio app

An app you build using the App Studio Publishing Portal. After you build and test your App Studio app, you can distribute it internally or submit it to one of the online app stores such as the Apple App Store or Google Play. Once approved, it will be made available to your customers.

App Studio issue

An App Studio issue is the digital equivalent of a book or a magazine. It’s a high-end, HTML5, interactive content file that you create in QuarkXPress, InDesign, directly in HTML5 or automatically from XML. This file is read by the App Studio Issue Previewer App or by the App Studio app you create on the App Studio publishing portal.

App Studio issue download

Occurs when an end consumer of your app downloads an issue of your publication to a device such as the iPad. For example, when a consumer downloads the March issue of your monthly magazine it constitutes one issue download. App Studio publication plans include a certain number of issue downloads with additional issue download bundles available for separate purchase.

App Studio issue download bundle

A bundle of issue downloads that can be purchased to supplement the issue downloads included in your publication plan.

App Studio Issue Previewer App

A free app that lets you test your App Studio issues on your mobile device. Download this app to your device from one of the app stores such as the Apple App Store or Google Play.

App Studio layout

A dedicated layout space available in QuarkXPress for the creation of App Studio issues. This layout type has specific properties to make the design process more efficient, such as the ability to manage layouts for multiple devices and orientations, as well as the ability to synchronize content and page properties between them. Note you will need QuarkXPress 9.5 or later.

App Studio Publishing Portal

The website where App Studio customers can manage their organization, users, publications, apps and issue files as well as test and collaborate on content.


Apple's mobile operating system. Originally developed for the iPhone, it has since been extended to support other Apple devices such as the iPad, iPad mini, and iPod Touch.

iTunes Store

Apple’s store for the purchase and download of content. It includes an App Store where customers can purchase and download apps.

Layout Family

A group of layouts that represents a single App Studio issue. One layout family might include a horizontal layout for the iPad, a vertical layout for a different type of tablet, and both vertical and horizontal layouts for a third type of tablet. All of the layouts in a layout family are bound to one another in terms of page count and sequence and share a common layout properties dialog.

Layout slideshow

A slideshow that displays the pages of a different layout in the project. This allows you to design each slide of a slideshow in QuarkXPress.

Scroll Zone

A scroll zone in an App Studio issue that provides a way for readers to view content by flicking or scrolling through the content in a single page. Scroll Zones are a unique feature of tablet content design, making them distinct from traditional, page-based print layouts. Once you set up a Scroll Zone, you can populate it with a variety of content, including text, large panoramic pictures, or a series of interactive elements. Scroll Zones can be used in multiple layouts within an App Studio layout family.


Unique Device Identifier. Essentially an iOS device serial number that can be retrieved through iTunes.
