I’ve tried a number of different writing software programs and like them all for different reasons. Storyist, Scrivener & Storymill are all variations of that tall, dark and handsome boyfriend. One may have a better sense of humor, one may be more handy around the house but you get the point. They’re the same, yet different in small measurable ways and a few not so small ways.
I won’t do a review because so many have been done before.
I will say, that Mariner Software is celebrating their 22nd anniversary and they’re offering 50% off their non-upgrade, desktop software. Try their free trial and if you like it, go for StoryMill. I love it for fiction (I like Scrivener for non-fiction).
It has the ability to break down a manuscript into scenes and has the flexibility of tagging them switching them around. It’s regularly $49.95 and on sale it’s $24.97 until 5/1/12. Just use Mariner22 at checkout.
