Writing Kit for iOS ($4.99 on the App Store), one of my small handful of go-to mobile text editing apps, has just released an update with Fountain support.
From the Writing Kit Blog:
Today I’m excited to announce Fountain support in Writing Kit 3.2. You can now open, edit, navigate, and preview Fountain screenplays right within the app.
This is exactly the kind of thing John and I hoped would start happening, and it’s happening fast.
