The highest-rated screenwiting app on the Mac App Store comes to iOS!

Slugline is a minimal, distraction-free environment for the most important part of screenwriting—the writing part.

Slugline works with plain text. It automatically turns your writing into a properly formatted screenplay, without you ever needing to press the Tab key.


⋮ Automatic formatting
⋮ Sync files with iCloud and Dropbox, or work locally
⋮ Works with iOS 11 Drag and Drop and the Files app
⋮ Printed on paper or PDF, your screenplay is indistinguishable from one made with apps costing much more
⋮ Helpful structure templates, including the famous beat sheet from Save the Cat!®
⋮ Slugline’s famous Integrated outlining
⋮ Notes, Scene Synopses, and Omitted text help keep you organized
⋮ Includes Courier Prime, a beautiful typeface designed for screenplays

Slugline uses the free and open Fountain screenplay format, which is nothing more than plain text.​ You can work on your screenplay anywhere, using any writing app. When you open it in Slugline again, everything will be there, properly formatted.​

Start with an outline, then seamlessly transition to writing scenes. Or jot down a placeholder for your third-act twist while you’re still crafting your opening pages. Slugline allows you to be as structured as you like, even if that means not at all.​

Slugline keeps getting better, and that's thanks to you! Slug us a line at with any questions or feedback you have, and follow us on Twitter at @SluglineApp.

Great writing tool, some *light* feature requests

Hey all at Slugline! This app is awesome. I can seamlessly switch between my MacBook and iPad when writing. Really love the integration with the new magic keyboard for iPad, too!

Only things to improve: User interface looks very “iPhone blown up to be and iPad app.” So, maybe some UI love in a future update?

Other than that, there is an odd issue where I cannot “delete/backspace” while holding the shift key. This is slightly annoying when typing character names. So, if that could be addressed, that would be greatly appreciated. Thanks! Keep it upppppppp

Fountain Screenwriting on iPad

I’ve been doing my screenwriting in Fountain for about 2 years now, and I’ve used Slugline on my Mac for a great deal of that work. However, my primary writing device is my iPad. The beauty of Fountain is that you can write in any word-processing app, so the lack of a full-fledged Fountain app for the iPad wasn’t a huge hurdle. But it always felt a bit hobbled.

Having used this app for a few hours, I can already say with certainty that this will be my most-used screenwriting app on any platform. Everything that was great about the Mac version is present here: the way the app formats as you type, the clean interface, the easy-to-use outline. And now I have those features on the devices I always have with me, my iPad and iPhone. Well worth the cost.

Not so much

I write episodic television and have been wanting to find an app that works well while I’m traveling and need to write. I found this one and thought I would give it a try. Although it seemed to be a good fit at first, I have come to loathe this app. Nearly every five minutes or so, it will close down, deleting the last paragraph or two of what has been written. Not only is it frustrating because I have to go back and rewrite what I just wrote, but it absolutely destroys the flow of writing, taking me out of the moment I was creating and forcing me to push refresh on the mental process, trying to get back into that moment. Not to mention it has no memory recall, so you have to fully write out every character name every time you use it, as opposed to it recalling the name after the first character or two like most other scriptwriting programs.

not a fan.

Hi justinhunt, thanks for taking the time to write a review. Crashing and losing work is the very last thing we want. Frequent crashes like the ones you’re experiencing are rare, but they are happening, and we are working on a fix for our next update.
