Learn about the customization screen, where you customize the reading environment of your new web, desktop, mobile app or hosted ebook, and emulate the app on different platforms and devices.

If you will be distributing your ebook as an EPUB, PDF, DOC file, or for Kindle, then skip customization and go straight to exporting your ebook. See Export Standard Formats.

In the Edit Screen, you wrote and designed your ebook. In the Customization Screen, you will design and customize your ebook as a web app, desktop app, mobile app, or hosted ebook. You can change the app's appearance, language, features and control bar.

To get to the Customize screen, click on the Customize tab in the upper left corner of the Kotobee Author window.  

The customization screen features a left panel to customize the app and a main window to view your ebook as an app running on different platforms and devices.

Main Panel

Preview and test your ebook and app on different devices. As your ebook may appear differently from one platform to another, try the app on different devices before you publish it, to get the best results for your viewers.
