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.

I Simply Can’t Rely On it

This hurts me to say, but this iOS version of what Slugline is has been the #1 hindrance of me no longer writing down screenplay thought on the go—which I know is their exact goal.

This app let me down numerous times in saving my screenplays incorrectly, jumbling all of my text around the entire pages, causing me to lose a large percentage of my work. I truly wanted to be patient, knowing fully that development comes with bugs, and maybe I hit a random one-off bug. But issues kept arising, and sadly I simply have lost trust and any faith working in this app.

I am, and have been, an advocate for their macOS app. It’s great and has never let me down. I have zero trust issues with Slugline there.

I don’t want to be too harsh with them as a company and tell the whole world that they’re terrible, because they’re not. They’ve done a lot right. I’ll try this app out again somewhere down the road.

Anyone reading this, note when this was written, because the issues may be fixed and you should feel comfortable giving it a go. :)

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.

Crazy Jump to Top of Script Issue

I used to love this app, but the last update has driven me to insanity and countless hours of therapy. Now when I type blissfully on the iPad version and the genius oozes out on the page, suddenly out of nowhere the curser jumps to the top of the doc, showing only the cover page info, leaving everything else totally blank (I can still type, but will only see what I typed if I return to the doc screen and then open the file again and then after endless scrolling get to return to the place I left off). This bug has dramatically slowed down my work to the point that I gave up on my dream to use my iPad Pro as a laptop replacement. I shall therefore disappointedly return to the old trusty laptop and fire up the more stable version of Slugline there.
