Produce submission-ready manuscripts and screenplays
Storyist for iOS is a powerful writing environment for iPad, iPhone, and iPod touch. It provides a rich text editor with support for comments, images, headers, footers, and style sheets so you can create properly formatted manuscripts and screenplays. And Storyist comes with manuscript and screenplay templates so you can focus on the writing, not the formatting.
Write, review, and revise on the go
Have a few minutes? Write a scene, review the day's pages, or annotate your manuscript with ideas for future revisions. One-tap Dropbox sync lets you quickly access your projects when and where you need them.
Work with your story at a high-level
Storyist lets you sketch out a story using index cards and then refine it with customizable plot, character, and setting sheets. When you're ready to put words on the page, Storyist can even display your index cards next to your manuscript as you write.
I love Scrivener, but its iPad app isn't available yet, and I've heard great things about Storyist for iPad from writers I trust.
