Fountain is not an app. It’s not even really a file format. It’s a simple set of straightforward rules for writing a screenplay in plain text. If you opened a text editing app, or even email, and started typing something that looked like a screenplay, chances are, you’re using Fountain.

INT./EXT.  BLOOM HOUSE - (PRESENT) DAY

The front door opens to reveal Will and Josephine on the porch with their bags.  REVERSE to Will's mother Sandra (53), surprised and a little annoyed. 

SANDRA
How did you get here?

WILL
We swam.  The Atlantic, it's not that big really.

That’s Fountain.
