Public apps contain content which is accessible to anyone who downloads the app.

App users do not need to register or sign in to access the app's content.

Public apps are usually distributed publicly via platform app stores, such as the iOS App Store and Google Play Store.

Public apps can contain content that is free to download, as well as monetised content (also known as in-app purchases).

Private apps contain content that is secured behind app user logins.

In order to access the content within a private app, app users must register and sign in with a username and password.

Private apps are sometimes used to distribute content internally within an organisation, or to deliver content that should not be publicly accessible.

However, private apps can also be offered to a larger audience by distribution through platform app stores.

Private apps allow for advanced app and dashboard features, such as segmented messaging and distribution, and actionable analytics.

For more information on these advanced features, see Managing Users and Liquid State App Analytics.

Content delivered through Liquid State apps is divided in to documents. Documents are individual volumes of content, which contain pages.

Documents are displayed within the app library screen, and can be individually downloaded by app users.

Publishing new documents or updating existing documents is a fast and simple process. You do not need to update your entire app to add new documents or update existing documents. This means you can avoid using platform app store portals, and simply manage your content from within Liquid State Cloud.

For information on publishing and updating documents, see How to: Publish or Update a Document

You can publish a documents as free content, or as a paid In-App Purchases (IAPs).

For information on selling your document as an IAP, see How to: Create In-App Purchases.

If you are planning to sell your app content, we recommend offering the app itself for free, with one or two documents available for free download. This gives users a good opportunity to sample your content, so they can assess whether they want to pay for additional paid documents (IAPs).

Pages are the building blocks of content in Liquid State apps. Each document is made up of one or more pages.

Pages in the Liquid State system are similar to pages in a printed book - except they are interactive, and responsive in size.

An app page can be as long as is necessary, and will resize to match the width of the screen it is being viewed on. App users can scroll through a page by swiping up or down, and navigate from page to page by swiping left or right.
