There’s no shortage of word processing software in the world, but few have the cult following that Scrivener does. Long available for OS X and Windows, it’s finally ready to be downloaded by anyone who owns an iOS device for $20.

I’m not much of a writer so I’ve never used Scrivener but many of the writers I know swear by it and have been waiting impatiently for this app for their iPads.
