When you open Beat on iOS, you are first welcomed by a splash screen, which allows you to create a new, empty document, create a document based on a template, or browse your existing files.
If you are unfamiliar with Fountain, you should first go through the Tutorial under Tutorial & Templates.
If you select Browse, you will enter the Document Browser View where you can navigate to a folder on your device or on cloud service, such as iCloud.
To create a new document in current folder in Document Browser, click on the red plus button at the top. Excuse the Finnish iOS – Oma iPad means My Own iPad.
After creating your first file, you are greeted with your fresh, new document!
Just start typing and your work is automatically saved on either your own device or on cloud.
Have fun!
