This Mac App Store version of StoryMill is English only and is El Capitan compatible.

Writing a novel is a creative process and like all creative processes, sometimes it’s hard to get started. StoryMill will be appreciated by the professional novel writer, but we really designed it for folks like you. With StoryMill, you can take your idea for mystery, romance, adventure, action or science fiction and turn it into that novel you know is within but just needs a little help getting out.

StoryMill is built so that you can develop your characters, locations and all the other elements of your story. You can set a daily writing goal and keep track of it using the Progress Meter. There are handy things to help you keep track of cliches and monitor how many times you use a word. There’s a place for all your research – add pictures, files and notes right into StoryMill – keeping it altogether and available whenever you need it.

StoryMill is the only novel writing app that includes a Timeline feature. Visually and interactively displaying a story across time, you can arrange the scenes of your novel in chronological order.

Bottom line...StoryMill gives you all the tools you’ll need for writing your own best seller.

Excellent Writing App

I am an intermittent writer since I have three young children. Each time I get an idea or come back to a scene, Storymill allows me to get back to where I left off effortlessly. I really enjoy the full screen writing view that is free of distractions.

Consistent Crashing

When I purchased this software it was because I was led to believe it was just what I needed to keep track of all of my notes for a novel I was writing. And for about a year it worked like a dream. But I have noticed in the years since that the app crashes 9 out of 10 times when I am trying to add information to specific sections. The constant crashing led me to stop using the software for months. Today I decided to open it back up and try using it again. And I counted 6 crashes before I basically just shut down the program. It angers me more than you can imagine that this application appears to still be for sale despite the fact that everyone reports just how much the app doesn't work. Also, the fact that this application hasn't been updated in nearly a decade leads me to second another reviewers comment that this just appears to be an abandoned app. It's honestly my opinion that this app should be pulled from all of apples app markets so that no one is essentially scammed into purchasing an application that rarely works the way it is intended to.

Two Days of Data Lost After Consistently Using Cmd S and "File Save"

I downloaded and began using StoryMill 4.0.5 three days ago. I printed and read the Instruction Manual. Pretty basic. To save, it's the usual two options - Command/S or File Save. I’ve been going at my project enthusiastically and I’m a fanatic about saving. I save constantly because I go back through my material frequently, cutting and pasting data between Characters and Scenes. Everything was running smoothly and when I finished up this evening, I closed my project. I remembered one more thing. I opened the project I just closed and all of my work for the last two days is missing - GONE! I went to Time Machine and it, too only has the data from the first day. After losing so much, I checked the Mariner Software StoryMill forum and found that MANY people suffered this difficulty over a year ago and it still has not been fixed. I wish I had read the forum before I trusted this software with my book. Frustrated and angry don’t begin to describe how I feel.
